1) the one making up the peak of the large triangle
2)the large triangle
are similar. That is because the 2 bases are parallel and corresponding angles are equal. The third angle at the peak is common. So by AAA they are similar.
Proportion
Therefore the sides are in proportion.
5/40 = 3/(2x + 10)
Solution
Cross multiply
5*(2x + 10) = 40*3
Remove the brackets on the left. Combine the right.
To find the with divide 102 by 17, we get 6. Then add 6+6+17+17 because we know this is a rectangle and it has 2 with sides and 2 length sides. We get the answer of 36.
