Question

find the value of x in this figure​

Answer 1

In the question, angle BAC=3x+40°
angle BCA=4x
and angle CBD=11x-60°

As we know, sum of interior angles of a triangle is equal to the opposite external angle.

Therefore,
A+C=CBD
=) 3x+40°+4x=11x-60°
=) 7x+40°=11x-60°
=) 7x-11x=-60°-40°
=) -4x=-100°
Therefore, x=100/4=25°

So, the value of x is 25°
