The angle of elevation to the top of a 15-story skyscraper is measured to be 4from a point on the ground 2,500 feet from the bui
alexandr1967 [171]

The point of observation is 2500 m away from the foot of the building.

The angle of elevation is 4°.

We need to find the height 'h' of the building.

With respect to 4°,

2500 is the adjacent side.

'h' is the opposite side.

The trigonometric ratio associating opposite & adjacent is tan.

We have

tan\theta =\frac{opposite}{adjacent}

tan4^{o}=\frac{h}{2500}

Cross multiplying we get

h = 2500 tan4°

h= 174.82 m

Option B) is the right answer.

Find the value of i77.<br> A) 1 <br> B) i <br> C) −1 <br> D) −i
Colt1911 [192]

assuming you mean i^{77} where i=\sqrt{-1}

ok, notice a pattern in the exponent

i^1=i=\sqrt{-1}

i^2=-1

i^3=-\sqrt{-1}=-i

i^4=1

i^5=i=\sqrt{-1}

hum, so it goes 1,2,3,4, then repeats

ok, so every 4, the cycle repeats

how far  up is 77 from a multipule of 4?

4*19=76

76 is 1 away from 77

so i^{77}=(i^{76})(i^1)=

(i^4)^{19}(i)=(1)^{19}i=i

the answer is B
