Answer:
7.5 feet
Step-by-step explanation:
large over small=64/27
r:4/3
4/3=10/h
4h=30
h=30/4
h=7.5 feet

Answer: When scaling something, only the lengths of the sides change, the angles would remain the same. The answer is stay the same.
Step-by-step explanation:
Answer: x = 11, y = 9
Step-by-step explanation:
To solve for x, set the sides equal to each other:
7x + 27 = 10x - 6
Add 6 to both sides:
7x + 33 = 10x
Subtract 7x from both sides:
33 = 3x
Divide both sides by 3:
11 = x
(Which is the same as x = 11)
Now, to solve for y, since they don’t give you the other side, you know that the straight line is 180° so:
7x + 27 + 9y - 5 = 180
Plug in your x:
7(11) + 27 + 9y - 5 = 180
77 + 27 + 9y - 5 = 180
Add like terms:
99 + 9y = 180
Subtract 99 from both sides:
9y = 81
Divide both sides by 9:
y = 9
Hope this helps!
i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.
So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL
ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the steps
