Answer:
x = 67.5°
Step-by-step explanation:
A circle's angles add up to 360°
So,
x+3x+90 = 360
4x+90 = 360
4x = 360-90
4x = 270
Dividing both sides by 4
x = 67.5°
Well a circle has 360 degrees and this question wants the degree of counter-clockwise.
I think first we subtract 69 from 360, since that is the rotation clockwise, to get the angle of rotation.
360 - 69 is 291 degrees
Answer: B
Explanation:
Equation of line y=mx+b
m = y2-y1/x2-x1 = 2-(-2)/1-(-1) = 4/2 = 2
b = (0,0)
y = 2x+0
y=2x
1- (9/2)
2- (-5/2)
3- (-4/3)
4-if it’s -8/3 divided by -1/2 then it’s (16/3)
You just have to multiply them by the second terms reciprocal
