The measure of two supplementary angles have a ratio of 4: 5 what is the measure of the larger angle

the larger angle is 100 degrees

Step-by-step explanation:

supplementary angles add to 180

4x+5x=180

9x=180

divide by 9

x=20

the larger angle is 5*x

5*20 = 100

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
