Answer:

D

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = 0.5h(a + b)

where h is the perpendicular height and a, b the parallel sides.

Given A = 120, then

0.5 × 8(a + b) = 120, that is

4(a + b) = 120 ( divide both sides by 4 )

a + b = 30 cm → D

31.12 in

<u>Explanation </u>
To get the length required, lets first find angle mF,
mF = 180 – (43 + 62) =75o
Now we can use the sin rule to find length DE.
a/sin⁡A =b/sin⁡B Where a and b are the length opposite to angle A and B respectively.
DE/sin75=22/sin⁡43
DE=(22 sin⁡75)/sin⁡43
DE=31.12 in

Find the slope of the line
natta225 [31]

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (2, 1)

m = \frac{1-4}{2+1} = \frac{-3}{3} = - 1
