Question

please answer the questions given below make the attachment

Answer 1

7x + 11x = 90
18x = 90
x = 5

7× 5 = 35°
11× 5 = 55°

Answer 2

let the ratio be in the form of x then the ratio will = 7x : 11x
complementary angels are sum of 90 degree angles. so according to question

7x + 11 x = 90
18x = 90
x = 90/18
x= 5

7* 5= 35
11*5=55
____________________________________

let the ratio be in X then the ratio will 4x: 11x
supplementary angels are sum of 180 degree angles. so according to question

4x+ 11x= 180
15x= 180
x = 180/15
x = 12
4*12= 48
11*12 =132
