Question

The ratio of the measures of the three angles in a triangle is 10:3:7. what is the measure of the largest angle

Answer 1

Step-by-step explanation:

Let angles be 10x , 3x , 7x

Sum of all angles of traingle = 180⁰

10x + 3x + 7x = 180⁰

20x = 180⁰

x = 9

Largest angle = 10x = 90⁰ Ans.

Answer 2

Answer:

10+3+7=20

10/20×180=90

3/20×180=27

7/20×180=63
