Question

# If and , find the value of x and

Hint:

- the base angle theorem states that if the sides of a triangle are congruent then the angles opposite these sides are congruent.

## The correct answer is: straight angle A equals 76 to the power of ring operator

- We have been given in the question that if 𝑚∠𝐵 = (5𝑥 + 7) ° and 𝑚∠𝐶 = (2𝑥 + 34) °
- We have to find the value of x and 𝑚∠A

Step 1 of 1:

In the given figure,

So,

x = 9

So,

= 5(9) + 7

= 52^{0}

And,

= 2(9) + 34

= 52^{0}

Now we know that the sum of angle of triangle is 180^{0}.

So,

So,

So,

^{0}

And,

^{0}

Now we know that the sum of angle of triangle is 180

^{0}.

So,
