Answer:

23

Step-by-step explanation:

The equation on the left will equal to 90 due to it being congruent to the angle with the square. Therefore, make the equation out to be 3x+21=90 and subtract 21 from both sides and that will give you 69. Divide 69 by three which will leave you with x=23

 8      x
16   100

Cross multiply 8 by 100 and you get 800.
Divide 800 by 16 and you get 50.
