Calculate the area of the triangle abc with altitude, cd, given: a(-6,-4), b(6,5), c(-1,6), and d(2,2). round your answer to the nearest tenth if necessary.

The answer to your question is 37.5 u²

Step-by-step explanation:

Formula

Area of a triangle =

Base

dAB =

dAB =

dAB =

dAB =

dAB = 15 u

dCD =  

dCD =

dCD =

dCD =

dCD = 5 u

Area

        = 37.5 u²

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
