Answer:
15.16047 cm
Step-by-step explanation:
notice that the smaller triangles ratio is 3 : 5
so the bigger triangle's bottom side has length 13 cm
so lets multiply 13 by (3/5)
we get 7.8
we can just use pythagorean theorem to find AB
x=6.6
13:5=x:3
33=5x
33/5=x
6.6=x
w=3 h=4
14=2w+2h w=(3/4)h
substitute
14=2(3/4)h+2h
distribute
14=1.5h+2h
simplify
14=3.5h
divide both sides by 3.5
4=h
plug into original equation
w=(3/4)4
w=3
reflection across y translate 1 unit to the right translate 6 units down
0.0915178...........
The answer is (6,12)
107x= 642
x=6
7•6 +2y=66
y= 12
(-6,-4)
Hope this helps! (:
