Question

x and y are two supplementary angles. If
supplymentary angle ofx is equal to half the
complementary of y then find x:y?​

Answer 1

Answer:

x:y = 135/45 = 3

Step-by-step explanation:

A/C, x+y=180          ---(1)

Also, 180-x=90-y

x-y = 180-90 = 90     ---(2)

(1) + (2)

x+y+x-y = 180+90

2x = 270

x=135

(1) - (2)

x+y-(x-y) = 180-90

x+y-x+y = 90

2y = 90

y = 45

Thus, x:y = 135/45 = 3
