Answer 6

oh so the similar figure is drawn to a different scale, not just rotated.
*bites lip* i Can't do this without the diagram in front of my face so, sorry

Answer 7

use ratios of corresponding sides

\[\frac{AB}{SR} = \frac{AD}{SP}....... \frac{10}{8} = \frac{AD}{9}\]

then

\[AD = \frac{10 \times 9}{8}\]

I'll let you find the answer

Answer 8

11 1/4
