Answer:
x+74=135
x=135-74=61(exterior angle of a triangle is equal to the sum of two opposite interior angle)
When you say two angles are complementary, they add up to 90 degrees.
Since two angles are the ratio 2:7, you can represent the smaller angle as 2x and the larger as 7x.
add them up as 2x+7x=90
2x+7x=9x 90/9x=10x
the angles are 2x=20 degrees and 7x=70 degrees
so the smaller angle is 20 degrees
Answer:
Part A) Multiply by 16
Step-by-step explanation:
Divide the hours by the walls, and you’ll have hours per wall.
(1 1/2) / (2/3)
= (1 1/2) * (3/2)
= (3/2) * (3/2)
= 9/4
He paints at 9/4 hours per wall.
