Answer:
36.87° and 53.13°
Step-by-step explanation:
the legs of the right triangle are 3 and 4 and the hypotenuse is 5
tan x = 3/4
x = arctan (3/4)
= 36.87° = measure on one acute angle
90 - 36.87 = 53.13° = measure of the other acute angle

4.0 in. 6.0 in. 4. On the floor plan shown at the right, 1.25 inches represents 2 feet. What is the actual length of the entire floor? a. Kitchen 4.0 in. 6.0 in. Dining Room b. What is the actual area of the entire floor? Explain how you found the area. length 4.0 in. Study Living Room 8.0 in. 2.0 in. Foyer width
Answer:
Part A= 19.2 Part B= 27.2
Step-by-step explanation:
4+8=12 divided by 1.25 equals 19.2
Width= 4+6=10 divided by 1.25=8
19.2+8= 27.2 is the total area
Hope this is right (:
Answer:
A. 19.2 Feet
B. 307.2 Feet
Step-by-step explanation:
A. First you divide 2 feet by 1.25 inches to figure out how much feet per inch.
2/1.25=1.6 feet
Meaning that 1 inch is 1.6 feet or 1 inch=1.6 feet
After that you add the length of 4 inches and 8 inches which equals 12 inches.
4+8=12 inches
After that you multiply 12 by 1.6
12*1.6=19.2
Meaning that the actual length is 19.2 feet
B. Once you find the length you add 4 inches and 6 inches which equals 10 inches.
Multiply 10 by 1.6
10*1.6=16 feet
After that to find the area you multiply 16 and 19.2.
16*19.2=307.2 feet

Below is a system of equations. Which method would you use to solve this? Why? Solve the problem, explaining each step.
x = y – 3
2x + y = 12
Answer:
(using substitution to solve the problem)
x=y-3
2x+y=12
2(y-3)+y=12
2y-6+y=12
3y=18
y=6
y=6
x=6-3
= (3, 6)
Step-by-step explanation:
using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.

Given:
In circle D, the measure of angle ADC is 108 degrees.
To find:
The measure of angle ABC.
Solution:
Central angle theorem: According to this theorem, the measure of central angle of an arc is twice of the measure of inscribed angle on that arc.
Using the Central angle theorem, we get
[tex]m\angle ADC=2\times m\angle ABC[/tex]
[tex]108^\circ=2\times m\angle ABC[/tex]
[tex]\dfrac{108^\circ}{2}= m\angle ABC[/tex]
[tex]54^\circ= m\angle ABC[/tex]
Therefore, the measure of angle ABC is 54 degrees.

An angle measures 26° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
103 & 77 degrees
Step-by-step explanation:
Supplements add up to 180 degrees.
I started at 90 & did:
90 + 13 = 103
(Because 13 * 2 is 26, but if you subtract 26 then the supplement will be 52 away & not 26)
180 - 103 = 77
103 - 77 = 26
Hope this helped. :)

Answer:
60
Step-by-step explanation:
10×2=20÷2=10×2=20 goes for the two top ones
20×2=40÷2=20×2=40 goes for the two bottom ones
40+20=60 is the answer
Answer:
60ft^2
Step-by-step explanation:
Split the area into two large triangles, the right and the left.
The base for the triangle is 10ft+20ft =30ft and we know the height is 2.
Since A=bh*1/2, A = 30*2*1/2. This equals 30. since there are two of these large triangles and they are equal, just multiply the area by 30.

3 puntos
Answer:
240 people
Step-by-step explanation:
[tex]\frac{60}{25} =\frac{x}{100}[/tex] (x represents people)
60×100= 6000 , 25 × [tex]x[/tex] = 25[tex]x[/tex]
