Answer:
x = 1.5
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin60° =
, then
sin60° =
=
=
( cross- multiply )
2x = 3
( divide both sides by 2 )
x = 1.5
you could either multiply straight away or you could simplify right then so that you wouldn't have to it later.
20/5 * 5/2
your answer would be 10 either way
8n-28
4(2n-7)
you cant factor this. There are no powers
