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°.
