Question

In triangle ABC, the measure of angle A is equal to the sum of the measures of angle B and angle C. The ratio of the measures of angle B and angle C is 2:7. Find the measure of the angle C. *​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

Let angle B=4x and angle C=5x.

Given, angle A=B+C=4x+5x=9x

We know that sum of angles in a triangle =1800

⇒9x+4x+5x=1800

⇒18x=1800

x=100

Hence, angles are A=9x=900;B=4x=400;C=500.
