Answer:
50º
Step-by-step explanation:
A triangles angles = 180º
Angle A = 40º
Angle C = 90º (this is a right triangle)
40º + 90º = 130º
180º - 130 º = 50º

Answer:
For #5: There are 3 children and 4 adults.
Step-by-step explanation:
Let x= number of children
y= number of adults
y = x + 1
x + y = 7
x + (x+1) = 7
x + x + 1 = 7
2x + 1 = 7
2x = 7 - 1
2x = 6
x = 6/2
x = 3
y = x + 1
y = 3 + 1
y = 4
Therefore, the number of children is 3 and the adults are 4.

Find the area of the figure below
Please help
============================================================
Explanation:
Rotate the triangle so that the side 17 cm is completely horizontal and the triangle is pointing upward. The 10.3 cm portion is the height. The base and height are always perpendicular to one another.
Area = (base*height)/2
Area = (17*10.3)/2
Area = 87.55 square cm
The sides 12 cm and 15 cm are not needed at all. They might have been put in there as a distraction.
Add the polynomials. Be sure to write your answer in standard form. (−4x3−5x+2)+(4x3+10)

Answer:
358in
Step-by-step explanation:
Use CAH or Cos()=(adj/hyp)
So Cos(36)=(290/h)
Re-Write the equation as h=(290/cos(36)) to get 358 inches
Which equation represents a line that is perpendicular to the line shown in the graph? (-5,6) (5,2)
Answer:
Y=5/2x-3
Step-by-step explanation:
The equation's slope is -4/10, which simplifies to -2/5. The reciprical of this, 5/2, is the slope of a perpendicular line. The first possibility you commented is the only one to have this slope.

A hawk takes flight from a mountain peak and flies 800 meters west. Then it takes a turn and flies 200 meters south. What is the distance and direction of the hawk from the mountain peak?
Answer:
the hawk has flow 824.62 meters southwest of the mountain peak.
Step-by-step explanation:
In order to find the distance we need to use the Pythagoras theorem
d^2 = 800^2 + 200^2
d= 824.6 m
we can find the direction by using the eq for a tangent
he opposite side is 200 m and the adjacent side is 800m
tan theta = opposite / adjacent
theta = arc tan (800/200)
The hawk is at a distance of 824.6m flying at an angle 76 degrees NE of the mountain peak.
The final location will be southwest of the mountain peek.
a2+b2=c2
a = 200
b= 800
c = √(2002+8002) = 824.62
So the hawk has flow 824.62 meters southwest of the mountain peak.

Answer:
The shorter leg, s, is the geometric mean between h and m
The longer leg, b, is the geometric mean between h and n
Step-by-step explanation:
By the right triangle geometric mean theorem, we have;
The altitude of a right triangle, 'h', which intersects with the hypotenuse side of the right triangle at a point such that it creates two segments, 'a' and 'b' on the hypotenuse side , then we have;
h = √(a·b)
Therefore, we have;
Description [tex]{}[/tex] Proportion
The altitude of ΔAYES is the geometric mean between m and n [tex]\dfrac{m}{a} =\dfrac{a}{n}[/tex]
a² = m·n → a = √(m·n)
The shorter leg, s, is the geometric mean between h and m [tex]\dfrac{m}{s} =\dfrac{s}{h}[/tex]
s² = m·h → s = √(m·h)
The longer leg, b, is the geometric mean between h and n [tex]\dfrac{n}{b} =\dfrac{b}{h}[/tex]
b² = n·h → s = √(n·h)
Jet had $63 to spend at Pet Smart. She spent 2/7 of her money on dog bones and the rest on squeaky toys to destroy. How much money she spend on the squeaky toys? (Just type the answer with the proper label, no complete sentence needed).
Answer:
She spent 45 dollars on squeaky toys.
Step-by-step explanation:
If we divide 63 by 7 we would get 9, then if we multiply that number by 2 for the bones, we are left with 5/7, finally if we multiply the 5 by 9 you would get 45, or 45 dollars.

Hi!
1/8 - 1/4 - 1/2 = 1/8 - 2/8 - 4/8 =

D. L'(-1,0)
Answer:
the answer from what I see in the picture is C
Please help me with this just type in the answers that apply
Answer:
All answers could be B, C and D
Step-by-step explanation:
According to the triangle inequality theorem, the combined length of two sides of a triangle cannot exceed the length of the third side. so:
13+8=21
Which means the sides that are less are A, B, C and D
Now A is smaller terms, if we try to use this to apply to a different way:
8+5=13
13=13
This means that the combined terms are NOT as small as the third side, and therefore this length cannot work. Therefore, the only ones left are lengths B, C and D

What kind of angles are 1 and 5 in the picture below?
Answer:
i guess the two numbers were obtuse angles
Angle 1 and angle 5 are corresponding angles.
What are the corresponding angles?When two parallel lines are crossed by another line, comparable angles are the angles that are created in matching corners or corresponding corners with the transversal (i.e. the transversal).
Given:
Two lines cut by line t.
And lines are not parallel.
So, angle 1 and angle 5 are corresponding angles.
Therefore, corresponding angles is the required statement.
