Answer:

D. 63 degrees

Explanation:

We can use the Trigonometric ratio ‘Tan’ to get angle B (because you have all 3 lengths, you can use any ratio. I used tan because it didn’t make use of the decimal number).

TanB = opposite/adjacent
TanB = 4/2
TanB = 2
B = Tan^-1(2)
B = 63.43°

Your answer is D.

Please feel free to comment if you do not understand the use of ‘Tan^-1’

(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-----------------------------\\\\
(x-2-4i)(x-2+4i)\implies [(x-2)-(4i)][(x-2)+(4i)]
\\\\\
[(x-2)^2-(4i)^2]\implies [(x^2-2x+4)-(4^2\boxed{i^2})]
\\\\\
[(x^2-2x+4)-(16\cdot \boxed{-1})]\implies [(x^2-2x+4)+16]

vlada-n [284]

The sales price is 85% of the original $2,200, which can be calculated as follows: .85(2,200) = 1870 Assuming you meant 15% discount price..
