Question

What is the value of X enter your answer in the box

Answer 1

x = 6

Explanation:

The sides are congruent; you can tell this by the lines marking the opposite sides (and, by viewing the shape, may recognize that this is a rectangle, which has congruent opposite sides).

Since these sides are congruent, we know that they are equal; therefore, we may set 40 = 5x + 10.

Now, solve with algebra!

40 = 5x + 10

30 = 5x

x = 6.

I hope this helped! :)
