Ehhh some parts were easy some hard . Defo better than paper 1

For me for some reason it wasn’t making sense .how do you find the side of a triangle if all your given is one angle and one side ? I tied using all my formulas , cos rule sin rule etc but it just wasn’t fitting

probably the hardest paper.
the question for the degrees was 210 degrees
paint was 4m^2 short
Simultaneous equations did anyone get?

X1 as 17/5 and Y1 as -4/5
X2 as 5 and Y2 as -2
agreed : )
