Answer:
x = 2
Step-by-step explanation:
All three angles are equal in measurements which means all sides of the triangle is also equal in measurement. To solve for x, simply equal the two expressions together and isolate variable x.
9 = 3x + 3
Isolate variable x by subtracting both sides by 3:
6 = 3x
Isolate variable x by dividing both sides by 3:
2 = x
Check your work:
9 = 3(2) + 3
9 = 6 + 3
9 = 9
Correct!
