Answer:
d
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent, then
2x = 6 ( divide both sides by 2 )
x = 3
and
3y = 6 ( divide both sides by 3 )
y = 2
Thus x = 3 and y = 2 → d
Answer:
2π r(15 + r ) = 650
Step-by-step explanation:
The formula for TSA of cylinder is 2πr (r +h)
so
The correct equation is
2π r(15 + r ) = 650
hope it helps :)
Answer:
y = 9
Step-by-step explanation:
m<1 + 2x = 180° because these angles are supplementary
61° + 2x° = 180°
2x = 180 - 61
2x = 119 divide both sides by 2
x = 59.5
Since f is parallel to s:
2x + (7y-2) = 180°
2×59.5 + 7y - 2 = 180
119 + 7y - 2 = 180
7y = 180 - 117
7y = 63 divide both sides by 7
y = 9
I can’t see the coordinates to help you do this but I’m going to try explaining it to you. in the first example on your sheet you can see 2 of the points of the triangle are 1 above the x axis. to reflect it over the x axis you’d go 1 below the x axis. To reflect over the y axis you do the same thing. Looking at the point (1,1) I think still on the triangle one. You see it’s 1 away from the y axis so you’d do the same thing as in the x. it’d be (-1,1).
