Answer:
63°
Step-by-step 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
=> x = 63
Hence,
The measurement of 5he third angle of the triangle is 63° (Ans)
