Question

in each figure, calculate the value of x​

Answer 1

Step-by-step explanation:

angle BAC = 180° - 70° ( Linear pair )

= 110°

180° = 110° + 38° + x (angel sum property of triangle)

x = 180° - 148°

x = 32°

Answer 2

☆Required Answer:-

• The value of x° = 32°.

Given:-

• Value of ∠B = 38°

To Find:-

• The value of x°

Concept:-

• The value of x° can be found by using Angle Sum Property of a triangle.Angle Sum Properties states that "Sum of all the three angles of a triangle is 180°".

• ∠A + ∠B + ∠C = 180°

Solution:-

In△ABC,

∠B = 38° (Given)

∠A = 110°(Linear pair formed from external angle; 180° - 70° = 110°)

∠A = 110°

∠B = 38°

∠A + ∠B + ∠C = 180°

110° + 38° + x° = 180°

148° + x° = 180°

x° = 180° - 148°

x° = 32°

Hence,

The value of x° is 32°
