Answer:

x = 5

Step-by-step explanation:

Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.

7x + 16 + 39 + 90 = 180


Simply.


7x + 145 = 180

     -145    -145

7x = 35

/7      /7

x = 5


^-^

Solution:

Note that:

  • 7x + 16 + 39 + 90 = 180

Simplify the equation:

  • 7x + 16 + 39 + 90 = 180
  • => 7x + 145 = 180
  • => 7x = 35
  • => x = 35/7 = 5
