Answer:

Step-by-step explanation:
we know that
The area of the trapezoid is equal to

step 1
Find the measure of angle DAE
m∠ADC+m∠DAE=180° -----> by consecutive interior angles
we have
m∠ADC = 134°
substitute
134°+m∠DAE=180°
m∠DAE=180°-134°=46°
step 2
In the right triangle ADE
Find the length side AE
cos(∠DAE)=AE/AD

step 3
In the right triangle ADE
Find the length side DE
sin(∠DAE)=DE/AD

step 4
Find the area of ABCD

we have

substitute

Answer:
4a. 15 wear braces
b. 20%
5a. 140 children - 400 - 120 = 280 ... 280/2=140
b. 35%
6a. Bob got $22.50. $45 / 2 = $22.50
b. $45 - $90 / 2 = $45
