Question

Someone help pls need this answered in a few minutes T^T

Answer 1

Cosine rule formula

`a^(2) = b^(2) + c^(2) - 2bc * \cos( a)`

*the small a in cos represents the angle

Conditions

You can only do Cosine rule if the angle is in between the 2 lengths

a^2=22^2+27^2-2(22)(27)×cos(105)

a^2=1520.477026 * so sqaure root to find a

a=38.99329462 *to 2 d.p.

a=38.99ft
