Question

One angle of a triangle is 70° and the other two are in the ratio
7:4. Find the other two angles.​

Answer 1

Answer:

the other two angles are 77 and 44 respectively.

Step-by-step explanation:

Let the common be X.

so, 7:4 = 7x + 4x

according to the question,

70+ 7x +4x = 180 (angle sum property of triangle)

=> 70+ 11x = 180

=> 11x = 180-70

=> x = 110÷ 11

=> X = 10

:. So, 7x = 11×7= 77

and

4x = 11×4= 44.
