Answer:
24
Step-by-step explanation:
The product of lengths from the point where the secants meet to the near and far circle intersection points is the same for both secants.
RQ·RC = RS·RT
8(27) = (3x)(8x)
9 = x^2 . . . . . . . . . divide by 24
3 = x
Then the length of interest is ...
TR = 8x = 8·3
TR = 24
Answer:
Step-by-step explanation:
Back
Area = L * W
L = 20
W = 8
Area = 20 * 8
Area = 160
2 Triangles
Area = 1/2 one smaller leg*other smaller leg
one smaller leg = 8
The other one = 15
Area = 1/2 8 * 15 = 60
But there are 2 of them 2 * 60 = 120
Base
L = 20
W = 15
Area = L * W
Area = 20*15 = 300
Front (slanted) Face
L = 20
W = 17
Area = L * W
Area = 20*17 <u> 340</u>
Total 920

Answer:
x =42.5
x+8 =50.5
3x+2 = 129.5
Step-by-step explanation:
The two angles shown are supplementary, so they add to 180
x+8 + 3x+2 = 180
Combine like terms
4x+10 = 180
Subtract 10
4x = 170
Divide by 4
x =42.5
x+8 = 42.5+8 = 50.5
3x+2 = 3*42.5 +2 = 127.5 +2 = 129.5
7/28 = 4/?
4*28 = 112. (a) = 16
112 ÷ 7 = 16.
7/588 = 4/?
4*588 =2,352. (b) = 336
2,352 ÷ 7 = 336
7/686 = 4/?
4*686 = 2,744. (c) = 392
2,744 ÷ 7 = 392
