Answer:
ACB = 100 degrees.
Step-by-step explanation:
Bisector means that the angle has been cut in 1/2. What that means is that each binomial has the same value. It means that they are equal.
Equation
15x - 25 = 60 - 2x Add 2x to both sides.
Solution
15x + 2x - 25 = 60 - 2x + 2x
17x - 25 = 60 Add 25 to both sides.
17x - 25+25 = 60+25
17x = 85 Divide by 17
17x/17 = 85/17
x = 5
That is not the answer, but it will get you the answer.
Use x = 5 to find the value of 60 - 2x
60 - 2*5
60 - 10
50
Since one of the angles inside ACB is 50 degrees, the other one must be equal to 50
The answer is ACB = 50 + 50 = 100
