A supplementary angle has three angles one being 44.4 another being 7x and another is 8x. I'm having a hard time.

x= 9.04°

7x = 63.28°

8x = 72.32

44.4° + 63.28° + 72.32° = 180°

Step-by-step explanation:

The sum of supplementary angles is 180°

Set up an equation with the given information, then solve for x.

44.4 + 7x + 8x = 180

7x +8x = 180-44.4

15x = 135.6 Divide both sides by 15

x = 9.04

Substitute for x and multiply by 7, then 8 to find the measures of the unknown angles.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
