      P = 2(L + W)
      P = 2(L) + 2(W)
      P = 2L + 2W
P - 2W = 2L
    2    2
¹/₂P - W = L

Solve for l.
p=2(l+w)

Flip the equation.

2l+2w=p

Add -2w to both sides.

2l+2w+−2w=p+−2w

2l=p−2w

Divide both sides by 2.

2l/2=p−2w/2

l=1/2p−w

Part A: The sum of the measures of UWZ is 90, so UWV and UWZ are_________ angles.

kiruha [24]

Answer: A. UWV and UWZ are complementary angles.

B.They do not overlap, so UWV and VWX are supplementary angles

Step-by-step explanation:

Complementary angles add up to 90.

Supplementary angles do not overlap.

The sector of a circle with a 12 in. radius has a central angle measure of 60°. What is the exact area of the sector in terms of

Lana71 [14]

That is angle/360 times area

area=pir^2
r=12 in this one
and angle=60
so
60/360 times pi12^2=1/6 times 144pi=24pi square inches

Which of the following facts, if true, would allow you to prove that lines l and m are parallel? NEED HELP

Damm [24]

Two parallel lines A and B are crossed by another line as shown in the attached figure. Angle 2 and 3 are equal, because they are opposite angles, while angle 3 and 7 are also equal, because they are corresponding angles, thus it is deduced that

angle 2 = angle 3

angle 3 = angle 7

So angle 2 = angle 7

<span>Hence fourth option is right.</span>
