Answer:

The largest angle is 90 degrees

Step-by-step explanation:

The three angles of a triangle add to 180

The ratio is 10 : 3: 7

Multiply each by x

10x, 3x 7x

Add them together and set equal to 180

10x+3x+7x = 180

Combine like terms

20x = 180

Divide by 20

20x/20x =180/20

x = 9

The largest angle is 10x

10*9 = 90

The largest angle is 90 degrees
