The side lengths of trapezoid ABCD are
the side lengths of trapezoid A'B'C'D'.
D
The line mis
the line segments
connecting the corresponding vertices of the two
trapezoid

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

hello,

as   long as they add up to 180 its correct.

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3
