Y1-y2 over x1- x2 you should be able to figure it out after this formula
The first one is "four tenths".
The second one is "four thousandths".
Your first equation would be:
65 + 3x - 10 + 2x = 180
Then simplify to get:
5x + 55 = 180
Subtract 55 from each side:
5x = 125
Now divide by 5 to find x:
x = 25
The measure of angle B = 65
The measure of angle C = 50
Hope this helps!! :)
Step-by-step explanation:
(5x + 2)(2x –3)
5x² – 15x + 4x – 6
5x² – 11x –6
