Answer:
x=180-68=112
So A and B are not correct.
180-112-27=41
y=41
So, C.
Answer:

Step-by-step explanation:
2y - 3x = 8
2y = 3x + 8
y =
x +4
It is similar to y = mx + b
Therefore m = 
To check whether a line has perpendicular slope we check the product of the slopes to be -1.
The perpendicular slope is 
Answer:
o -1/2
Step-by-step explanation:
Slope is the ratio of rise/run.
We the line passes through (0,3) and (6,0)
Rise = y2 - y1 = 0 - 3 = -3
Run = x2 - x1 = 6 - 0 = 6
Slope = -3/6 = -1/2
Answer:
? = 32.20422
Step-by-step explanation:
We know the adjacent side and the hypotenuse
cos ? = adj / hyp
cos ? = 33/39
cos ? = 11/13
Taking the inverse cos of each side
cos ^ -1( cos ?) = cos^-1(11/13)
? = 32.20422
A2+B2=C2
12(2)+B(2)=27.1(2)
24+B=54.2
-24 -24
——————
B=30.2
Answer is 30.2
I hope this helps
