Question

Find the measure of the unknown angle in each of the following:
​

Answer 1

Answer:

let, the unknown angle be, x

therefore,

In the given ∆

x + 65° + 50° = 180°

{reason : angle sum property of triangle}

x + 115° = 180°

x = 180° — 115°

x = 65°

therefore, the measure of the unknown angle = 65°

Step-by-step explanation:

Answer 2

Let the unknown angle be x

In the given ∆

x + 65° + 50° = 180°

{reason : angle sum property of triangle}

x + 115° = 180°

x = 180° — 115°

x = 65°

therefore, the measure of the unknown angle = 65°
