Question

One angle of a triange is 19 degrees, a second angle is 98 degrees. What is the measurement of the third angle?

Answer 1

63°

Explanation:

Angle sum property = 180°

=> 19 + 98 + x = 180

=> x = 180 - 117 = 63°

Answer 2

63°

Explanation:

Given,

Measurement of one angle of a triangle = 19°

Measurement of 2nd angle of the triangle = 98°

Let,

The third angle be = x

As we know,

Sum of all the angles of a triangle is 180°

Therefore,

By the problem,

=> 19° + 98° + x = 180°

• (On shifting like terms to one side )

=> x = 180 - 98 - 19

• (On subtracting)

=> x = 63

Hence,

The measurement of 5he third angle of the triangle is 63° (Ans)
