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:
20/24
Step-by-step explanation:
If you simplify, you get 5/6.
Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.
Answer:
1-141
2-39
3-139
4-98
5-102
6-50
7-74
8-83
9-95
10-162
Step-by-step explanation:
<span>c) 0.65*(P-35); $107.25
This can be easily found by elimination and plugging in.
We know it can't be "d" because that's the only answer with $95.00. It can't be "a" either because it starts with (P-0.35), unlike the other answers. Now you're left with "b" and "c".
We know that the original price is 200, which we plug in for "P".
b) </span><span>0.65*(P)-35
</span><span>0.65*(200)-35
130-35 = 95
This doesn't equal </span><span>$107.25, so it can't be the answer.
</span>
c) <span>0.65*(P-35)
</span><span>0.65*(200-35)
</span>0.65*(165) = <span>$107.25
Therefore the answer is C.</span>
