As we know from the last post that we'll be using cosine.
This will be the rearranged formula :
(Side) Cos ( Angle) = Side
8 × Cos (70) = 2.73616....cm
multiply 15430000 by 25%
25% = 0.25
15430000 x 0.25 = 3857500
3/m-2=7/m+2
3(m+2)=7(m-2)
3m+6=7m-14
3m-7m=-14-6
-4m=-20
m=20/4
m=5
8
Substitute x = 3 into the expression
=
= 8
