Question

What is the value of x? Enter your answer in the box.

Answer 1

Answer : The value of x is, 80°

Step-by-step explanation :

As we know that the sum of interior angles of a triangle is equal to $180^o$.

$\angle A+\angle B+\angle C=180^o$

Given:

$\angle A=30^o$

$\angle B=70^o$

$\angle C=x^o$

$\angle A+\angle B+\angle C=180^o$

Now put all the given value of angle in the above expression, we get:

$30^o+70^o+x^o=180^o$

$x^o+100^o=180^o$

$x^o=180^o-100^o$

$x^o=80^o$

Therefore, the value of x is, 80°

Answer 2

Answer:

80 degrees

Step-by-step explanation:

all triangles have the angles of 180 degrees, so by that logic, 180-70-30=80.
