Answer:
Length 7 feet and Width 5 feet
Step-by-step explanation:
we know that
The area of the rectangle ( a dining room table) is equal to
where
substitute
Apply difference of squares right side
Remember that the length cannot be a negative number
so
x=2
<em>Find the length</em>
<em>Find the width </em>
The measure of angle E is (b) 50°
<h3>How to determine the angle measure?</h3>
The given parameters are:
- ΔCAB is similar to ΔCED
- AB and ED are parallel
The similarity of the triangles implies that:
- angle C = angle C
- angle A = angle E
- angle B = angle D
From the figure, we have:
angle A = 50
Substitute angle A = 50 in angle A = angle E
angle E = 50
Hence, the measure of angle E is (b) 50°

Given a = {1, 2, 3, 4, 5, 6, 7, 8, 9} and b = {2, 4, 6, 8} what is AUB?
cestrela7 [59]
<span>AUB is the union of sets A and B.
It is a set that contains every element of set A and every element of set B.
Write a set that has all the numbers in both sets A and B. Be sure to write each number only once even if the number appears in both sets A and B.

H= 12.4
I assume this is a rectangular prism. the formula is V=l*w*h
plug-in the known values
<span>V=3758.75 W=24.25 L=12.5
</span><span>3758.75 =24.25*12.5*H multiply terms
</span><span>3758.75=303.125H divide both sides by 303.125
12.4=H</span>
