Final answer:
The equation (3x - 15)° = 105° is solved by first adding 15 to both sides, then dividing by 3, resulting in the value of x being 40.
Step-by-step explanation:
The equation given is (3x - 15)° = 105°. To solve for x, you need to follow these steps:
- First add 15 to both sides to isolate the term with x:
3x = 105 + 15 - Then, simplify the right side:
3x = 120 - Finally, divide both sides by 3 to solve for x:
x = 120 / 3 - Simplify the division:
x = 40
Therefore, the value of x in the equation is 40.
