100 POINTS HELP ASAP NOW!!!!!! Find the value of x in each case.

Zepler [3.9K]

Answer:

x = 22.5°

Step-by-step explanation:

The interior angle at E is (180 -4x), the supplement of the exterior angle there, 4x. The sum of angles 2x and (180-4x) will be equal to 6x, because alternate interior angles at transversal BE are congruent:

2x +(180 -4x) = 6x

180 = 8x . . . . . . . add 2x and simplify

22.5 = x . . . . . . . divide by 8

The value of x is 22.5°.

7) Find the area of the shaded region:

aleksandr82 [10.1K]

Answer:

Step-by-step explanation:

The area of the biggest rectangle =

$(9x - 2)(2x + 7) = 18 {x}^{2} + 63x - 4x - 14 = 18 {x}^{2} + 59x - 14$

The area of the of the smallest rectangle inside=

$3x(x + 12) = 3 {x }^{2} + 36x$

Then the area of the shaded region =

$18 {x}^{2} + 59x - 14 - (3 {x}^{2} + 36x) = 18 {x}^{2} + 59x - 14 - 3 {x}^{2} - 36x = 15 {x}^{2} + 23x - 14$

So, we choose B.
