The formula for the area of a trapezoid is a=1/2(b1+b2)h
So 10*5 = 50 *4 = 200 then divided by 2 is 100 so the answer is 100
Cos(<span>θ) < 0, so we know it would be in Quadrant 2 or 3
then csc(</span>θ) = 257, but csc(θ) =

= 257
==> sin(<span>θ) =

it is positive, so now we can determine that is in Quadrant 2
sin(</span>θ) = opp./hyp both of opp and hyp are positive but adj suppose to negative because that way it leads the cos(<span>θ) < 0
</span>cos(<span>θ) = adj/hyp
</span>Pythereom to find the adj:

cosθ =

tanθ =

cos<span>θ = </span>
X=8 & z=66
because vertical angles are congruent
0.75 is equal to 6\8
5.8 is > 4\5
a decimal greater than 5\8 is 1.2
0.2 > 1\4
0.7>0.6
a decimal smaller than 6\8 is 0.01
The one that is not equal to -7\5 is -11\5
The answer is D
48 x 8.25% = 3.96
Now add 3.96 + 48
Answer 51.96
