Question

ratio of two supplymentary angles is 7:12 find the measurement of those two angles​

Answer 1

Answer:

66.3 and 113.6

Step-by-step explanation:

Assume the two angles are in the ratio 7x:12x.

Since angles are supplementary, 7x+12x=180.

Hence your answer.

Answer 2

Answer: Let 7x = small angle  

let 12x = big angle  

7x + 12x = 180  

19x = 180  

x = 180/19

x =   9.47

Small angle = 7(9.47) = 66.2

Big angle = 12(9.47) = 113.64
