Question

9. The ratio of the measures of the three angles

10
in a triangle
is 10:3:7. Find the measure of the
largest angle.

Answer 1

90 degrees

Explanation:

10 + 3 + 7 = 20

10/20 x 180 = 90 degrees

Hope this helped :)

Answer 2

The largest angle is 90 degree[10]

Explanation:

Let 10:3:7 be x

10x+3x+7x = 180 [ angle sum property of a triangle ]

20x = 180

x=180/20

=9/1

=9

10x=10*9=90

3x=3*9=27

7x=7*9=63

90>63>27

therefore the largest angle is 90 degree.
