Question

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 150 to the power of ring operator

- We have been given in the question diagram of a triangle named ABC where ∠ABC=60.
- We have to find out angle A.

Step 1 of 1:

We have a given figure

In this figure,

4x = 20

x = 5^{0}

So,

= 15^{0}

And

7(5) - 20

= 15^{0}

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

So,

In this figure,

^{0}

So,

^{0}

And

^{0}

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

^{0}.

So,
