M=y2-y1/x2-x1
m=12-4/-6--2
m=8/-4
m=-2
Answer:
The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;
= 3 + 4 + 5
= 12 units
a. <u>12 units</u> = 240 cm
The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.
b. <u>1 unit </u>= 20 cm
If 12 units are to 240 cm, 1 unit is;
= 240/12
= 20 cm
c. Length of red side;
Red side has length of 5 units. 1 unit is 20 cm.
Length in cm is;
= 5 * 20
= 100 cm
The answer is 1/4 as 3/4-2/4 is 1/4
the the negative angle is -(2π-π/4)= -\frac{7 \pi }{4}
Answer:
I got .08 when solving this, I may have made a mistake and if so I am truly sorry!
