Follow me please and I back follow u

Answer 2

Step-by-step explanation:

In a triangle, the total of all the 3 angles will be 180 degrees

When the ratio values of 5,13 and 2 are added, we get 20

Hence, for a unit value of ratio, the angle is 180/20= 9 degrees

Measures of the 3 angles are,

For the ratio value 5, it is 5 x 9 =45 degrees

For the ratio value 13, it is 13 x 9 =117 degrees

For the ratio value 2, it is 2 x 9 =18 degrees

Thus, the measures of the 3 angles are 45, 117 and 18 (all in degrees
