A surveyor is conducting measures to see how wide a road is
drek231 [11]

Answer:

D) 45 ft

Step-by-step explanation:

The two triangles are shown below.

Given:

BC = 60 ft, CD = 24 ft and DE = 18 ft.

Since, the two triangles are similar, their corresponding sides are in proportion.

So, \frac{AB}{DE}=\frac{BC}{CD}=\frac{AC}{CE}

Now, consider the proportion of sides,

\frac{AB}{DE}=\frac{BC}{CD}\\AB=\frac{BC}{CD}\times DE\\AB=\frac{60}{24}\times 18\\AB=\frac{60\times 18}{24}=45\ ft

Therefore, the distance between A and B is 45 ft.

A + b = 10 <br> a - b = 2
____ [38]

Answer:

a = 6 , b = 4

Step-by-step explanation:

a + b = 10................equation 1

a - b = 2..................equation 2

Solving equation 1 and 2 we get

a + b = 10

<u>a - b =  2</u>

2a = 12

a = 12/2

Therefore a = 6

Now

putting a = 6 in equation 1

6 + b = 10

b = 10 - 6

Therefore b = 4

Divide this to get a decimal:

17 / 25 = 0.68

Now multiply by 100 to get a percent:

0.68 * 100 = 68%
