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
