Isosceles and a right triangle
Answer:
value of a = 6.93 m
hence , (b.)
Step-by-step explanation:
the given triangle is a right angled triangle, so
by using trigonometry.
=》
and we know,
=》
so, by above values of tan ( a ) we get,
=》
=》
=》
=》
=
=》
hence, a = 6.93 m
You're original equation has a -81, so the factored form will have to have a positive and negative multiplying one another to achieve that...
f(x) = x(x + 9)(x - 9)
