Question

What is the value of x?



Enter your answer in the box.

Answer 1

80 degrees

Explanation:

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

Answer 2

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°
