Find the area of a triangle whose vertices are (1,-1), (-4,6) and (-3,-5).

a - base

b - exponent

so,

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
