What is the area of a triangle whose vertices are d(3, 3) , e(3, −1) , and f(−2, −5) ? enter your answer in the box.

The base length is 3 - (-1) = 4 units   (vertical side DE).

The height is 3 - (-2) = 5 units   (horizontal segment from F to the intersection with vertical segment DE).

The area of the triangle is ()*5*4 = 10 square units.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
