Question

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

Answer 1

The little lines crossing the sides of the triangle mean that the 2 sides are identical.

When 2 sides are identical the 2 bottom angles are the same, so 73 and 8y-7 are both 73 degrees. 73 +73 = 146 degrees.

This would mean the third angle ( 6x+4) needs to equal 180 - 146 = 34 degrees.

Now we can find X:

6x+4 = 34

Subtract 4 from each side:

6x = 30

Divide each side by 6:

x = 30/6

X = 5
