Question

one angle of a triangle is 78° degree and the other angles are in the ratio 7:10 . Find their measures. ​

Answer 1

Answer:

Two angles of the triangle are in ratio 7 : 10

Let the angles be 7x and 10x

Now, sum of angles of triangle = 180

78+7x+10x=180

17x=102

x=6

Thus, angles are 42
