Given:
Triangle DEF
To find:
The perimeter of triangle DEF.
Solution:
Coordinate of D = (-1, 1)
Coordinate of E = (2, 1)
Coordinate of F = (-1, 4)
Distance formula:
<u>Distance of DE:</u>
Here,
d = 3 units
<u>Distance of EF:</u>
Here,
d = 4.2 units
<u>Distance of FD:</u>
Here,
d = 3 units
Perimeter of ΔDEF = DE + FE + FD
= 3 + 4.2 + 3
= 10.2 units
The perimeter of triangle DEF is 10.2 units.
Answer:
Step-by-step explanation:
For this I would find two friendly points like (60,10) and (70,30). Now we will plug in for the slope-intercept formula .
So...
Now we plug in and solve...
So the slope will be 2.
