Question

X,y and z are three angles lying on a straight line
If y=x+z find the value of y

Answer 1

Answer:

y = 90°

Step-by-step explanation:

if y = x + z

y = z + x

so if y = 90°

then x = 45°

z = 45°

So x + z = 90°

45° + 45° = 90°

Answer 2

Answer:

MARK ME BRAINLIEST

Step-by-step explanation:

We have,

∆x=2x ∆y

∆z=3x ∆y

let consider angle y be A

Angle x +Angle y+angle z=180°

2a+a+3a=180°

6a=180°

a=180/6

a=30°

a=angle y

m /y=30°

m/x=60°

m/z=90°
