A triangle has an angle that measures 80°. The other two angles are in a ratio of 9:11. What are the measures of those two angle

Alekssandra [29.7K]

Answer:

The answer is 45° and 55 °.

180° - 80° = 100°

Then add the two numbers from the ratio:

9 + 11 = 20

The divide 100 from 20.

100 ÷ 20 = 5

Then multiply it to two numbers from the ratio:

9 × 5 = 45 and 11 × 5 = 55

I hope it helps.
