Answer: x = 67.5 ft

Explanation:

Following the statements you can draw the triangles mnp and mab.

1) Both are similar triangles with the common vertex m, and with these corresponding sides:

- segment mn corresponding to ma
- segment np corresponding np
- segment mp corresponding mb

2) So, by side-angle-side theorem

segment ma         segment mb
------------------ = ---------------------
segment mn          segment mp

3) You know:

- segment mn = 71.5
- segment ma = 71.5 - 22 = 49.5
- segment mb = x
- segment mp = 97.5

4) Therefore:

    x            49.5
--------- =  ----------
97.5            71.5

5) Solve for x:

x = 97.5 * 49.5 / 71.5 = 67.5

Answer: x = 67.5 ft.

HW #35: similar polygons
Alex73 [517]

Answer:

Q 9:

Because the two polygons are similar so AB ≈ PQ = SR

Scale factor is 25/20 = 1.25

Perimeter of ABCD = 14+20+14+20 = 68

We can find the length of SP by multiplying the scale factor with the AD so

SP = 14 * 1.24= 17.5

Perimeter of PQRS = 17.5+25+17.5+25 = 85

-----------------------------------------------------------------------------------

Q 10:

Because the two polygons are similar so AD ≈. EH

Scale factor is 7/14 = 0.5

Perimeter of ABCD = 12+14+13+26 = 65

Because the two polygons are similar so DC ≈ HG

and our scale factor is 0.5 so HG = 13/2 = 6.5

Perimeter of EFHG = 6 + 7 + 6.5 + 13 =  32.5

----------------------------------------------------------------------------------

Q 11:

The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers). And the formula for finding the Geometric mean of two numbers a and b is

\sqrt{a*b}

So geometric mean of the 8 and 10 can be found as

\sqrt{8*2} = \sqrt{16} = 4

-----------------------------------------------------------------------------------

Q 12:

Similarly we can using the above formula of finding the geometric mean of 5 and 45 as

\sqrt{5*45} = \sqrt{225} = 15


-------------------------------------------------------------------------------

Q 13:

and we can find the geometric mean of 6 and 30 by using the same formula

\sqrt{6*30} = \sqrt{180} = 13.41
