Question

Two angles of a triangle measure 68° and 54º. Find the third angle of the triangle.​

Answer 1

Given

• Two angles of a triangle are 68° and 54°.

⠀

To find

• Measure of third angle of the triangle.

⠀

Solution

• In this question, angle sum property of a triangle is used. As we know that, sum of all angles of a triangle is 180°.

⠀

⇛ Let the third angle of the triangle be x.

⠀

According to the question

⠀

→ 68 + 54 + x = 180

⠀

→ 122 + x = 180

⠀

→ x = 180 - 122

⠀

→ x = 58°

⠀

Hence,

• The measure of the third angle of the triangle is 58°.

Answer 2

QuestioN :-

Two angles of a triangle measures 68° & 54° . Find the third angle of triangle .

AnSweR :-

Given :-

• The two angles of a triangle are 68° and 54°

To find :-

• The third angle of triangle

AnsweR :-

We know that , sum of all angles of a triangle is 180° .

So ,

=> ∠A + ∠B + ∠C = 180°

=> 68° + 54° + ∠C = 180°

=> 122° + ∠C = 180°

=> ∠C = 180° - 122°

=> ∠C = 58°

Hence , the third angle of triangle is 58°
