See the figure of aabc with auxiliary lines added.
if c is the base of aabc, the height is
sin(a) = 7
the previous statement is leading to the derivation of
which area formula?
area aabc =

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

step-by-step explanation: it is d
