Question

The ratio of two supplementary angles is 4:5, find the measures of each angle ?

Answer 1

suplmentary angles are who add to 180 degress

Answer 2

so 2 angles =4.5

Answer 3

a/b=4/5
a+b=180

Answer 4

a=4/5b
a+b=180

Answer 5

9/5b=180

Answer 6

b=100
a=80

Answer 7

80/100=4:5

Answer 8

100, 80

Answer 9

Can you explain that step by step ?

Answer 10

suplmentary angles are who add to 180 degress create system of equations: a/b=4/5 and a+b=180. a=4/5b a+b=180. substitute a: 9/5b=180 b=100. a=180-100=80. b=100 a=80
