Answer:
C. 85 degrees
Step-by-step explanation:
(set the equations equal to each other):
6x-25 = 4x+15
(solve for x):
2x = 40
x = 20
(plug in x back into the equation):
6(20)-25 = 120-25 = 95
(subtract your value from 180 degrees (180 degrees is a line)):
180-95 = 85 degrees
Check the picture below.
make sure your calculator is in Degree mode.

Using proportions, it is found that Felipe needs 23.625 meters of wood to make that many birdhouses.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
To make an amount, he needs 5 1/4 meters = 5.25 meters. How many meters he needs to make 4 1/2 = 4.5 times the amount?
5.25 x 4.5 = 23.625 meters.
Felipe needs 23.625 meters of wood to make that many birdhouses.
