Find the measure of each angle in the garden.

Question

the second angle of a triangle garden is 4 times as large as the first. The third angle is 45 degrees less than the second angle.

Answer 1

f represents the measure of the first angle

4f represents the second angle

4f - 45 represents the third angle

 

f + 4f + 4f -45 = 180

 

Can you solve for f and answer?
