Question

one angle of a triangle is equal to the sum to other two angles are 7:8. find the angle of the triangle.
( Ans: 90,42,48)​

Answer 1

Answer:

• ∠A = 90°

• ∠B = 42°

• ∠C = 48°

Given :

• One angle of a triangle is equal to the sum to other two angles are 7:8.

To find :

• The angle of the triangle =?

Step-by-step explanation:

Let the other two angles of the traingle be 7 x and 8x.

One angle is equal to the sum of other two angles, So (7x + 8x) = 15x.

We know that,

Sum of all angles of traingle = 180°.

So, ∠A + ∠B + ∠C = 180°

Substituting the values, we get,

15x + 7x + 8x = 180

30x = 180

x = 180/30

x = 6

Hence,

∠A = 15x ➮ 15 × 6 = 90°

∠B = 7x ➮ 7 × 6 = 42°

∠C = 8x ➮ 8 × 6 = 48°
