P = 2(L + W)
P = 22
L = 2W - 4
22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm
L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm
Answer:
1/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-2)/(3-(-4))
m=1/(3+4)
m=1/7
So 3 times the measure of a small angle
3x + x= 180
4x = 180
X= 45
3(45) + 4(45) = 180
Hope this helps!
