Answer:
Try useing a therom.
Step-by-step explanation:
27:In the first question you could use SAS which means side angle side because D is the midpoint and it tells you that ab and bc are equal.
Same for 28
So the surface area of a box has this equation: A = 2 (wl + hl + hw)
w = width = 38
l = length = 38
h = height = 0.25
Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
= 2926 square meters
Answer:
the length of the ramp is 25 meters
Step-by-step explanation:
Joe is making a ramp. Ramp forms a right angle triangle with the base
So we use Pythagorean theorem to find the length of the ramp
AC^2(hypotenuse) = AB^2 + BC^2
Length of ramp is the hypotenuse = 
=
= 
= 
= 25
so the length of the ramp is 25 meters
X=2
subtract 5x on both sides
-2x=-4
divide by -1 on both sides
2x=4
divide by 2 on both sides
x= 2
