Question

Find the value of x. A. 60 B. 50 C. 40 D. 30

Answer 1

We can see that two sides of that triangle area equal

so, their corresponding angle will also be equal

now, we know that

sum of all angles in any triangle is always 180

so, we can get equation as

$x+100+x=180$

now, we can solve for x

$2x+100=180$

$2x=80$

$x=40$

so, option-C..............Answer
