Find the value of x in the triangle below.

x = 20

Step-by-step explanation:

To solve this problem, we need to know that a triangle has three angles which sum to equal 180°.

If you pay attention to the lower right hand corner of the triangle, you will see a "box." In math, this box means that the degree measure of that angle is equivalent to 90°. Therefore, because we see the box, we know that means there is a 90° angle in the triangle.

We are also given a 70° angle. This angle is in the lower left hand corner.

So, we can set up an equation to solve for x because we are given two of the three angles needed in order to determine the third angle measure.

90 + 70 + x = 180

160 + x = 180

x = 20

Step-by-step explanation:

What we have to note is that all angles in a triangle add up to 180°.

The sign of a right angle is that little box in the right. That means that the angle there is 90°.

Since we know two out of the three angles, we can find the other by adding what we know and subtracting from 180.

Adding what we know:

Subtracting from 180:

So the value of x is 20°.
