Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
Answer:
a² + b² = c²
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
A)106°- angle at the centre is half of the angle at the circumference
b)74°- when a tangent meets a radius a right angle is created(90+90+106)= 286 360-286= 74°
Answer:
20%
Step-by-step explanation:
Probability=5/(5+12+8)*100=5/25*100=20%
Answer:
y=3x-2
Step-by-step explanation:
Because the equation for slope intercept form is y=mx+b!
