Answer:

53.2 feet

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

tan(50^o)=\frac{AC}{BC} -----> by TOA (opposite side divided by the adjacent side)

substitute the values

tan(50^o)=\frac{h}{40}

solve for h

h=(40)tan(50^o)

h=47.7\ ft

therefore

The height of the pole is

h+5.5=47.7+5.5=53.2\ ft

Dan pays £714.73 a year on his car insurance
LenaWriter [7]

Answer:

The Current Insurance cost = $685.43

Step-by-step explanation:

Given that Dan pays £714.73 a year on his car insurance.

Reduced Percentage = 4.1%

so

Reduced Amount =  4.1% × 714.73

                             = [4.1 / 100] × [714.73]

                             = 0.041 × 714.73

                             = $29.30

The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.

so

Current Insurance cost = 714.73 - 29.30

                                       = $685.43

Therefore, the Current Insurance cost = $685.43
