The answer is d=<span>= 1/2 (a+b) 2nd power </span>
Set up a system of equations:
B=2+3C
B+C=90
The variable B is already solved, so plug into bottom equation:
2+3C+C=90
2+4C=90
4C=88
C=22
Plug C back in:
B+22=90
B=68
So B is 68 degrees and C is 22 degrees
Hope this helped!
12 (don't take my answer because it's been awhile since I've fine a question like that but I'm pretty sure it's 12)
Answer:
m - 8/3
Step-by-step explanation:
Find the slope of the line between (-3,1) and (6,7) using m = (y2 - y1) / (x2-x1)
which is the change of "y" over the change of "x"
m = (7 - (-1) / 6 - (3)
m = 8/3
