Answer:

40° and 50°

Step-by-step explanation:

Sum the parts of the ratio, 4 + 5 = 9 parts

Complementary angle sum to 90°

Divide 90° by 9 to find the value of one part of the ratio

90 ÷ 9 = 10° ← value of 1 part, thus

4 parts = 4 × 10° = 40°

5 parts = 5 × 10° = 50°

The angles are 40° and 50°

Answer:

Proportionality Constant = k = $\frac{1}{9}$

Step-by-step explanation:

Equation is:

$y = \frac{x}{9}$

=> $y = (\frac{1}{9} ) x$

Comparing it with $y = kx$ , where k is the proportionality constant, We get:

Proportionality Constant = k = $\frac{1}{9}$

We are able to set 4x+32 equal to 6x-8 because these are congruent vertical angles

4x+32=6x-8
4x+40=6x (add 8 to both sides)
40=2x (subtract 4x from both sides)
X=20 (divide both sides by 2)

Then we plug in 20 for x into 6x-8 to find the answer

6(20)-8
=120-8
=112

Hope this helps!
