Answer:
1.38
Step-by-step explanation:
tan Ø = 2/3
Ø = tan⁻¹(2/3)
Ø = 33.69
sin 33.69 ≈ 0.55
cos 33.69 ≈ 0.83
sin Ø + cos Ø ≈ 1.38
C: Rotation of 90 degrees.
X-4y=0
Turn to slope intercept form y=mx+b
-4y=-x
y=x/4. Slope in this case is 1/4.. because it’s 1x/4 and 1/4 is in front of x. So the slope is 1/4
W- (3,4)
Z- (-1,1)
X-(-1,-3)
Y-(-4,1)
