Question

In triangle XYZ, angle X are 20 degree more than angle Y. If angle Z = 38 degree, find the angle for X and Y.

Answer 1

let angle X be 'a' 
ATQ 
angle Y=28+a 

GIVEN ANGLE Z = 38 DEGREE 

SO BY ANGLE SUM PROPERTY 

ANGLE X + ANGLE Y + ANGLE Z = 180 DEGREE 

therefore a+20+a+38=180 
2a + 58 = 180 
2a = 180-58 
2a = 122 
a = 61 

therefoe angle X = 61 and angle Y = 81 

hope its right
