The answer to your question is: x = 19
Step-by-step explanation:
The angles are vertical, so they measure the same
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60
6x - 3x = 60 - 3
3x = 57
x = 57/3
x = 19
Answer:
Multiply 2/3 and your number. If you have a whole number, convert it to a fraction by putting it over a denominator of 1. When multiplying fractions, calculate numerator times numerator, then denominator times denominator. For example, to find two-thirds of 18, multiply 2/3 x 18/1 to get 36/3.
