Question

If two of the angles of a triangle are 30 and 70 degrees, the third angle measures...?

Answer 1

Answer:

80°

Step-by-step explanation:

Since a triangle has three angles that add up to 180°, you add the two given angles and subtract it from 180°.

1

70° + 30° = 100°

2

180° - 100° = 80°
