Find the measures of the given angles or the lengths of the given sides. m< b=3y, m< e=6y-12

Use the inverse of the function y=x^2-18x to find the unknown value [tex]y = \sqrt{bx + c \: + d} [/tex]

In the diagram, the ratios of two pairs of corresponding sides are equal to prove that almn - axyz by the sas similarity theorem, it also needs to be shown that x 6 z un z zz un = 2x zləzz lezy

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
