Question

Fine the value of the x in the triangle shown below.

Answer 1

28

Explanation:

Add 79 and 73 to get 152 then subtract that from 180.

Answer 2

x=28

Explanation:

The interior angles of a triangle must add to 180 degrees

Therefore,

79+73+x=180

Combine like terms by adding 79 and 73

152+x=180

To solve for x, get x by itself. Since 152 is being added to x, subtract 152 from both sides. This will cancel the 152, and leave x by itself.

152-152+x=180-152

x=28

So, x is equal to 28 degrees
