Answer:it is 2
Step-by-step explanation:
Answer:
x = 5.5
Step-by-step explanation:
Based on the Mid-segment theorem of a triangle, we would have the following:
EF = 2(AB)
AB = 7
EF = 2x + 3
Plug in the values
2x + 3 = 2(7)
Solve for x
2x + 3 = 14
Subtract 3 from each side
2x + 3 - 3 = 14 - 3
2x = 11
2x/2 = 11/2
x = 5.5
If you scroll up I answered a previous question like this in the same subject
First you have 2 triangles and 3 rectangles so you will get the area of 5 of them
for the first face of rectangle
2.5x10=25
second face
2x10=20
for the third rectangle which is the base
10x1.5=15
for the two triangles
1/2xBasexHeight
1/2x1.5x2=1.5 ——> this is for one triangle so multiply by 2 to get both triangles
1.5x2=3
so the total surface area is equal to 3+25+20+15=63
