Cos(30)=x/20(squarerootof)3 (lolz, sorry bout that xd)
x= 30
sin(30)=y/20(squarerootof)3
y=17.32
you'll have to change Y into a fraction or square root I think...
but yee
Answer: a=19
Step-by-step explanation: In order to solve this question, we must first take out the parenthesis, we can do this by taking 1/3 and multiply it by a and 5. This will give us 8=1/3a+5/3, with this we can subtract 5/3 on both sides of the equation, which will then give us, 19/3=1/3a. Last, we can divide 19/3 by 1/3 giving us 19 as our final anwser. a=19
This is just stuff you have to memorize, I can’t really explain much further than product always means multiplication. The “product of” means k*m
X is Kevin; Y is Dan
X = 3Y
X - 4 = 5(Y - 4)
3Y - 4 = 5(Y - 4)
3Y - 4 = 5Y - 20
+ 4 +4
4 cancels each other out.
3Y = 5Y - 16
- 5 -5
5 cancels each other out.
-2Y = -16
/2 /2
Y = 8
X = 3Y;
X = 3 x 8;
Thus,
X = 24;
Kevin(x) is 24
Community property of addition because -6 + 6 would equal zero
