Answer:
52 square units
Step-by-step explanation:
For this you need the length of CB and the length of DA.
|CB| = √(10²+2²) = 2√26
|DA| = √(10²+2²) = 2√26
area of ABC = base · height / 2 = 2√26 · 2√26 / 2 = 52
Answer:
Step-by-step explanation:
Through -3 , -2 slope = -2/3
y1 = -2 & x1 = -3 and m = -2/3
y - y1 = m(x - x1)
y - (-2) = -2/3(x - (-3))
y + 2 = -2/3(x + 3)
Multiply each term by 3
3y + 6 = -2(x + 3)
3y + 6 = -2x - 6
3y = -2x - 6 - 6
3y = -2x - 12
