Answer:
y = 65°
Step-by-step explanation:
z = 70° (corresponding angels are equal)
y + z = 135° (exterior angle theorem of a triangle)
y + 70 = 135 (substitution)
Subtract 70 from each side
y + 70 - 70 = 135 - 70
y = 65

the answer is 3.75 I'll explain ,</span><span>here: 1.5 times 2 equals 3 now go to a different section and divide 1.5 by 2 then add the two together it will look kind of like this:</span>
<span>(1.5*2)+(1.5/2)=3.75</span>
In the first step when the student did -2x-3 they didn’t make the sign positive. It should be 4=-2+6, not 4=-2-6
Answer:
h = 9
Step-by-step explanation:
cylinder A = 
*4 = 113.0973355 
Cylinder B = 113.0973355
113.0973355 = 
*h
113.0973355 / 4 = h
8.999999999998 = h
I think b/c of the rounding error of rounding off pi, that h= 9
I am sick there toooo someone plez helppp
