Question

In Triangle XYZ YZ = XY and angle Y = 80°, then determine the
measure of angle X.

Answer 1

Answer:

please send figure of this question

Answer 2

Answer:

Angle X = 50°

Step-by-step explanation:

Given

In ∆XYZ, YZ = XY

=> Angle YXZ = Angle YZX

[Angles opposite to equal sides are equal

& ∆XYZ is an Isosceles Triangle]

Let Angle YXZ = Angle YZX = a

Then, according to the Angle Sum Property of Triangles,

Angle YXZ + Angle YZX + Angle XYZ = 180°

=> a + a + 80° = 180°

=> 2a = 180° - 80°

=> a = 100°/2 = 50°
