Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that 
is the same as a*d = b*c
is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4
Bottom rectangle = 10*7 = 70
Top rectangle = 8*7 = 56
Side rectangle = 6*7 = 42
Side triangle = (1/2)*8*6 = 24
Side triangle = (1/2)*8*6 = 24
--------------------------------------------------
Total surface area = 70+56+42+24+24 = 216
As three hours divided by 2 is 1.5 hours, we know that to find how far the person walks in hours, we simply have to double the distance the person walked in 1.5 hours.
2.4*2=4.8
The person walked 4.8 miles in three hours.
Does that make sense?
Answer:
10x + 6 ≥ 42
Step-by-step explanation:
SinC=(8/17)
solve for C = arcsin(8/17)
