I think it’s either 4 or 20
5 x 4 =20
6 x 4 =20
The equation for a trapezoid is A = a+b all over 2 times h
So, you would simply substitute.
A=15
B=12
H=8
15+12/2 (8)=
27/2 (8)=
13.5 (8)=
108.
ns +sb = 5.4 cm
sb = en so en can be plugged in for sb
therefor es = 5.4
The answer to the question is d.
The green arrow thing is a ray. So, question b. is a ray. So the dot would be B and the arrow would be C.
