Answer:
20
Step-by-step explanation:
the triangles are similar so the sides are in proportion
(x/10)=(12/6)
6x=10*12
x=10*12/6=20
Your answer is 7/40 or 0.175
52 lbs you get the answer by adding the two weights of the bags
Angles of a triangle add up to 180 degrees and then we take away the right angle
180-90=90
5x+5x=10x
90/10=9
x=9
