Answer:

63

Step-by-step explanation:

add the given then subtract from 180

If m∠1 = 98° and m∠2 = 19°, the value of m∠3 will be 63°.

It should be noted that the sum of the angles that are in a triangle is 180°. Based on the information given, we've been given two angles to be 98° and 19°.

Therefore, the value of the third angle will be:

= 180° - (19° + 98°)

= 180° - 1117°

= 63°

Therefore, the third angle is 63°.
