An equilateral triangle has 3 equal sides. Since one side is 14 cm, then all sides are 14 cm. You multiply 4 by 3 and you get your answer.
14*3=42. The perimeter is 42cm.
Answer: 40°
Step-by-step explanation:
You add 90° for the right angle and 50° for the other and subtract from 180°
Answer:
y=2/15x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-5-(-3))/(-15-0)
m=(-5+3)/-15
m=-2/-15
m=2/15
y-y1=m(x-x1)
y-(-3)=2/15(x-0)
y+3=2/15(x)
y+3=2/15x
y=2/15x-3
Answer:
Step-by-step explanation:
L = Length
W = Width
W = 2L
2W + 2L = 174
2(2L) + 2L = 174
6L = 174
L = 29 ft
W = 2(29) = 58 ft
