Answer: The answer is.......
2.875
Use the triangle formed by the height of the trapezoid to find the lengths of the two sides of the trapezoid and the length of b2:
tan(60)=oppositeadjacent . Adjacent=5tan(60)=2.89 cm.
This finds the base of the triangle, which can be added twice to b1 to find b2: b2=8+2.89+2.89=13.78 cm.
Now, use the same triangle to find the length of the sides.
sin(60)=oppositehypotenuse . Hypotenuse=5sin(60)=5.77 cm.
Lastly, add all of the lengths together: b1+b2+2(l)=8+(2.78+2.78+8)+2(5.77)=33.32 cm.
Answer:
Bk = 65
Step-by-step explanation:
BK as we can see is 4x + 1
If two triangles are similar, the ratio of the corresponding sides are the same
Thus;
2x+7/27 = 4x + 1/45
45(2x + 7) = 27(4x + 1)
90x + 315 = 108x + 27
108x-90x = 315-27
18x = 288
x = 288/18
x = 16
From the question;
BK = 4x + 1
BK = 4(16) + 1
BK = 64 + 1
BK = 65
Answer:
$1.60
Step-by-step explanation:
6/4.80 1/?
?= 0.8
by writing out the fractions and solving the proportion you will find that one bag costs $0.8. Multiply that by 2 and you get your answer which is $1.60
