#6**+3 **

3. This one is a little hard to see, NSS....

The small right triangle at the bottom left has a hypotenuse of 10 and one leg of 6

So.....the other leg = sqrt (10^2 - 6^2) = sqrt (100 - 36) = sqrt (64) = 8

And this right triangle and the one at the top are related in the following way ......

6 / 10 = h / 16 ......multiply both sides by 16......

16*6/ 10 = h

96/10 = h

9.6 = h

4. Area = (1/2)Base x Height = (1/2)(13)(4) = (1/2)(4)(13) = 2 * 13 = 26 in^2

Just as Singerforthelord found !!!!!
