option 3
they are corresponding angles and are congruent
Answer:
x = 20
4x = 80
5x = 100
Step-by-step explanation:
5x + 4x + 5x + 4x = 360
18x = 360
x = 20
check the picture below.
now we start off with a square, namely a rectangle with all equal sides, so if we cut it in half, like in the picture, and each half-side is x long, then the longer sides are 2x long, as you see there, and we know the perimeter is 21.
so since we know each side is 7 units, then the area is just 7², or 49.
Okay, so basically we have:
w as width; and 6+w as length
Perimeter=2w+2l
just substitute it with the values of width and length
P=2w+2(6+w)
P=2w+12+2w
P=4w+12
So, the answer is letter B.
Answer:45/32.
Step-by-step explanation:
51-6=45. Thus, our answer is 45/32.
