This triangle is isosceles (indicated by the tick marks), which means its base angles are congruent; given this, you can set them equal to each other to solve for x:

3x = 5x - 30
-2x = -30
x = 15

Answer:
x = 15

Hope this helps!

A special 8-sided die is marked with the numbers 1 to 8. It is rolled 20 times with these outcomes: 3 4 5 2 7 1 3 7 2 6 2 1 7 3

Greeley [361]

The prime numbers on the dice are 1,2,3,5 and 7 , the theoretical probability is
$\frac{5}{8}$ , which is 62.5%, the number of prime numbers in the outcome is 15, so the experimental probability is $\frac{3}{4}$ , which is 75%, the difference between the experimental probability and the <span>theoretical probability is 12.5%.</span>
