Question

36. If angle A of triangle ABC is 2 times the sum of other two angles. Also the ratio of angle B to angle C
is 3:7. Find the angles.
If EP and FP are the bisectors of angle E and angle F. Find​

Answer 1

Answer:

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 =180  

0

 

⇒9x+4x+5x=180  

0

 

⇒18x=180  

0

 

x=10  

0

 

Hence, angles are A=9x=90

;B=4x=40  

0

;C=50
