Question

In ΔXYZ,if YZ = YX and ∠Z = 42°, then find the value of ∠Y.

Pls Answer Fast!!

Answer 1

Answer:

Do u mean? If LY = LZ??

if so then let LY = LZ be x

x + x + 42 = 180

2x = 180 - 42

2x = 138

$x = \frac{138}{2}$

x = 69°

Answer 2

Answer:

96°

Step-by-step explanation:

As YZ=YX opposite angles are equal so angle X =42

total degree of a triangle is 180°

so angle Y = 180- angle X+Z

= 180-84=96
