Use the area of the rectangle to find the area of the triangle.
5 ft
8 ft

B

Step-by-step explanation:

5*8 equals 40, the area of the square. Divide by 2 to get the triangles area. which is 20

B is correct

Step-by-step explanation:

8*5=40

40*1/2=20

B is correct

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
