Question

Given the following square, solve for x.
(7x+13) °

Answer 1

x = 11

Explanation:

square = a plane figure with four equal straight sides and four right angles.

so

7x + 13 = 90

7x = 90 - 13

7x = 77

x = 77 : 7

x = 11

------------------------

check

7 x 11 + 13 = 90

90 = 90

the answer is good
