Using the sine rule:
sinx/37 = sin42/31
sinx = 37 x sin42/31
x = (i dont have a calulator but use inverse sign to get this answer)
(-8x)<span> ÷ (-4)=0
First you have to divide both sides by -4:
2x</span><span> ÷ 1=0
Now divide both sides by 1 so that the left side can be eliminated:
2x=0
</span>Now divide both sides by 2 so that the left side only has x:
x=0
Rebecca gained a level after all 3 turns, at the end of turn 2 she has 6 points
Step-by-step explanation:
x = the number
4×(x+3) = 16
x + 3 = 4
x = 1
