Question

find the value of x

​

Answer 1

Question :-

• find the value of x

Concept :-

• In this question, we can see that there's a triangle ( three sided polygon ) and we can see that one side of the triangle is 90° [ right angle ]. And one side is gives as x and other side is not mentioned so we will alao consider it as x. We will add all the three sides and subtract it by 180° [ sum of a triangle ] .

Solution :-

★ Sum of a triangle = 180° ★

=> 90° + x + x = 180° [ sum of a traingle ]

=> 90° + 2x = 180°

=> 2x = 180° - 90°

=> 2x = 90°

=> x = 90° /2

=> x = 45°

Therefore, the value of x is 45°.

___________________

Verification :-

=> 90° + 45° + 45° = 180° [ sum of a traingle ]

=> 90° + 90° = 180°

=> 180° = 180°

Joyful learning!!!⛅
