Question

find the missing angle, e =???​

Answer 1

Answer:

to find angle: e

Step-by-step explanation:

180*- 56*=e

e=124*

Answer 2

Answer:

e = 31°

Step-by-step explanation:

We know that

sum of all angles of a triangle = 180°

In the left side triangle,

Two sides are equal.

Hence, two angles will be equal in the triangle.

Let both equal angles be x.

A/Q,

56° + x + x = 180°

=> 56° + 2x = 180°

=> 2x = 180° - 56°

=> 2x = 124°

x = 124°/2 = 62°

Now,

In right side triangle,

First angle = 180° - 62° = 118° [Sum of straight angles = 180° ]

In this triangle two sides are also equal,

Hence, two angles of it will be equal.

Second angle = Third angle = e

A/Q,

118° + e + e = 180°

=> 2e = 180° - 118°

=> 2e = 62°

=> e = 62°/2 = 31°

Therfore, e = 31°
