Answer:
42 or B
Step-by-step explanation:
So the top triangle is similar to the whole triangle by AA similarity. It has a ratio of 1:2. So 4x+2:4x+44 is 1:2. So 8x+4=4x+44. Simplifying, we get 4x=40 or x=10 So 4x+2=42
100
the first one
Area of a trapezoid = h * (b1+b2/2)
= 10 cm * ((20.75cm + 16.25cm)/2)
= 185 cm²
Therefore the area of the trapezoid is 185 cm²
46
p=40+0.15(40)
=40+6
Answer: 3pi
Guessed and it was right, sorry don’t have an explanation.
