One angle of a triangle measures 95°. The other two angles are in a ratio of 8:9. What are the measures of those two angles?

Answers

Answer:

40 degrees and 45 degrees

Step-by-step explanation:

If you subtract 95 degrees from a 180-degree triangle, you are left with 85 degrees. To proportionally split them, find two values that add to the same value. Since 40 and 45 make up 80 and they multiply by two to make 80:90, these are the two measures.
