Answer:
0.5
Step-by-step explanation:
just divide in a calculator
First of all, you surely do have a lot of incorrect grammar in your statement. I can't understand a word that you are asking.
The angles of a triangle add up to 180 degrees
65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====
m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50
28.27431 = x + 2
