A triangle has one angle that measures 19 degrees, one angle that measures 118 degrees, and one angle that measures 43 degrees.
What kind of triangle is it?
A. right triangle
B. obtuse triangle
C. acute triangle
D. equilateral triangle
Answer:
B. obtuse triangle
Step-by-step explanation:
Obtuse triangles are triangles with one obtuse angle and two acute angles. Define obtuse angles as angles over 90 degrees and acute angles as angles less than 90 degrees.
In this triangle:
118 degrees - obtuse angle
19 degrees - acute angle
43 degrees - acute angle
Thus, this triangle is an obtuse triangle.

someone please help or i’ll be failing geometry this year
Step-by-step explanation:
I don't know what constructions you were taught.
a "similar" triangle is a triangle with exactly the same angles as the other triangle, but the lengths of all sides are stretched or shortened by the same scaling factor f.
by saying 1:2 she means the second triangle should have sides with twice the lengths of the first triangle (f=2).
and the extra challenge - same basic thing. she allows you to pick one of the two triangles as reference. and then you need to draw a third triangle (again with the same angles) with the side lengths extended by the scaling factor f of 4/3.
I would draw the triangles right on top of each other with the same starting corner (let's call it A) for all 3.
we would get the triangles ABC, AMN and AXY.
the points B and C would be then halfway on AM and AN.
and M and N would then a bit before X and Y on AX and AY.
the beauty is, you only need to construct 2 sides of every new triangle down to the new endpoints. the third side is automatically scaled correctly, and you only need to connect these new endpoints.
let's assume you draw a triangle (just very simple) ABC with all side lengths being 3. so, AB=3, AC=3, BC=3.
now you draw AMN by extending AB and AC to a side length of 6 (f=2) creating M and N, and you connect M and N.
and then you can create the third triangle AXY by extending AM and AN by a factor of 4/3 to side lengths of 8 (4/3 × 6 = 8) creating new end points X and Y. and you connect X and Y.
and that is it. all 3 triangles are similar (the same angles), and all sides of a triangle have the same length ratio to the sides of the other triangle(s).

x = 3y
4x + 5y = 34
solve for x and y
Help help
Answer: y=2 and x=6
Step-by-step explanation:
x=3y
4x+5y=34
From equation ( 1) x=3y thus substituting in eqn(2)
4(3y)+5y=34
12y+5y=34
17y=34
y=34÷17=2
Thus y=2
Putting y=2 in eqn(1)
x=3y
x=3(2)
x=6

evaluate the expression 5-(6+3i)+2i
Answer:
-1 - i
Step-by-step explanation:
First, start by distributing the negative sign(-1), and you get:
5 - 6 - 3i + 2i
Next, combine the like terms, 5 & -6, and -3i & 2i.
This gives us: -1 - i
A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 90 pounds. The truck is transporting 50 large boxes and 65 small boxes. If the truck is carrying a total of 4950 pounds in boxes, how much does each type of box weigh?
Answer:
small = 30 pounds
large = 60 pounds
Step-by-step explanation:
two equations can be derived from the question
x + y = 90 eqn 1
50x + 65y = 4950 eqn 2
x = small box
y = big box
multiply equation 1 by 50
50x + 50y = 4500 eqn 3
subtract equation 3 from 2
15y = 450
y = 30
substitute for y in equation 1
y = 60
Oscar rides his skateboard 5/8 mile in 1/4 hour. How fast, in miles does he ride his skateboard
Answer:
2.5 miles per hour
Step-by-step explanation:
[tex]\frac{1}{4}\times \frac{5}{8}[/tex]
Step 1: Apply the fraction rule: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]\frac{1}{4}\times \frac{5}{8}=\frac{1\times \:5}{4\times \:8}[/tex]
Step 2: Set up the fraction
[tex]\frac{5\times \:4}{8}[/tex]
Cancel the numbers: [tex]\frac{4}{8}=\frac{1}{2}[/tex][tex]=\frac{5}{2}[/tex]Convert to decimal[tex]\frac{5}{2} = 2.5[/tex]Therefore, Oscar's speed is 2.5 miles per hour.
Company 1 says that they will complete the job for $12 per foot of fencing. Company 2 says that they will charge you $250 for the first 100 feet of fencing and $15 for each additional foot. Determine the cost of fencing for both companies.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Company 1:
Variable cost= $12 per foot
Company 2:
Fixed cost= $250
Variable cost= $15 per foot
To determine the total cost of each company, we need to use the following formulas:
Company 1:
Total cost= 12x
x= number of feet
Company 2:
Total cost= 250 + 15x
x= number of feet
For example, for 150 feet:
Company 1:
Total cost= 12*150= $1,800
Company 2:
Total cost= 250 + 15*(150 - 100)
Total cost= $1,000

Membership to a music club costs $130. Members pay $5 per music lesson and nonmembers pay $15 per
music lesson. How many music lessons would have to be taken for the cost to be the same for members and
nonmembers?
Non-members would have to take 9 to equal 135
Members would only take 1 plus the membership fee to equal 135.
I don't know if that's what it's asking for but I hope it helps.

If PR is 4, WQ is 8, and QR is 5, SP = ___ units
Answer:
From the attached graphic, we can see:
(SP + PR) * PR = (WQ + QR) * QR
SP * PR + PR^2 = WQ * QR + QR^2
4 SP + 4*4 = 8 * 5 + 25
4 SP + 16 = 65
4 SP = 49
SP = 49 / 4
SP = 12.25

Which expression is equivalent to 6 (3x + 4)
Answer:
E
Step-by-step explanation:
Answer:
18x+24
Step-by-step explanation:
Use the distributive property
6, 8, 11, 12, 2x – 8, 2x + 10, 35, 41, 42, 50
are in ascending order. If the median is 25,
find the value of x.
Ans: 12
Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
x = 16.5 as the median in this term is 2x-8
and 2x-8 = 25
25+8=2x
33=2x
x=[tex]\frac{33}{2}[/tex]
= 16.5
Step-by-step explanation:
this answer says 12 which is false

degrees
Answer:
72 degrees
Step-by-step explanation:
Find the diagram attached. We are to find the length of the arc
Measure of arcABC = rtheta
16π = 10 theta
theta = 16*180/10
theta = 16 * 18
theta = 288degrees
central angle = 360 - 288 = arc AC
central angle = 72degrees
Hence the arc measure of AC is 72 degrees

If the area of the rectangle shown is given by the expression 3x2 + 72 - 6and the width is (a + 3), which of the
following would represent the length? Remember: A = lw (Hint: Box method multiplication may be helpful here!)
Answer:
3x - 2.
Step-by-step explanation:
The length = area / width.
The area 3x^2 + 7x - 6 = (3x - 2 )(x + 3)
so the length = (3x - 2 )(x + 3 ) / x + 3
= 3x - 2.

Determine the volume of the space in the tank that still needs to be filled with water if the water is ⅓ ft. Deep
Answer:
11 1/9 ft^3
Step-by-step explanation:
find the complete question in the attached image
volume of the tank = length x width x height
2 x 5 x 1 2/3
2 x 5 x 5/3 = 50/3 = 16 2/3 ft^3
If the tank is 1/3 filled with water, the volume that needs to be filled with water is 1 - 1/3 = 2/3
volume that needs to be filled with water = 2/3 x volume of the tank
2/3 x 50/3 = 11 1/9 ft^3
