Question

One angle of a triangle is equal to the sum of the other two. If the ratio of the other angles is 7:8, find the angles of the triangle.​

Answer 1

Answer:

We know both triangle are in ration 7:8

We can take first angle as 7x other as 8x

other angle is sum of these (15x)

So 7x + 8x + 15x

Hence 15x = 180 ( Angle Sum)

x = 180/15

=x = 6

first angle is 7 x = 7 x 6

=42

second angle is 8x = 8 x 6

=8x = 48

third angle is 15x = 15 x 6

=15x = 90
