Answer:
x = 9 1/3
Step-by-step explanation:
We can use the ratios of similar triangles to solve
x 7
----------- = ------------
x+8 13
Using cross products
13x = 7(x+8)
Distribute
13x = 7x+56
Subtract 7x from each side
13x-7x = 7x+56-7x
6x = 56
Divide each side by 6
6x/6 = 56/6
x= 28/3
x = 9 1/3
Answer:
D. 54
Step-by-step explanation:
54 + 54 = 108, and 72 + 180 equals 180 degrees.
This is due to the fact all angles in a triangle add up to 180 degrees.
It’s reflected across the y axis
Answer:
first figure (top left)
Step-by-step explanation:
For similarity:
1) Each corresponding angles of both figures should be same.
2) Each sides must also be in proportion.
So by following both rules we can se that figureABCSE is similar to first figure (top left)
