Step-by-step explanation: because if you get 45$ for breaking 1 and lose 20$ for paying for it you will just get 25$ for breaking each board
They can help you simplify the fraction
4 × ( 4 + 9 ) = 2 × ( 2 + x )
4 × 13 = 2 × ( 2 + x )
2 × 2 × 13 = 2 × ( 2 + x )
2 × 26 = 2 × ( 2 + x )
Divide both sides by 2
2 × 26 ÷ 2 = 2 × ( 2 + x ) ÷ 2
26 = 2 + x
Subtract both sides 2
26 - 2 = 2 - 2 + x
x = 24
Congruent triangles are exactly the same, meaning they have the same side length, and thus same angles. Everything is exactly the same, as easy as it gets :)
So, you can compare the two pictures to get the informations you need:
, since it is a right angle
, as we can see on the right by comparison
. In fact, the angles of a triangle sum to 
, so we have 
. So, 
yd, as we can see on the left by comparison.
Finally, we can compute 
using the Pythagorean theorem:
