Answer:

sin = \frac{\sqrt{5} }{3}

Step-by-step explanation:

                                             <u>SOH CAH TOA</u>

Where:

s = sin

c = cos

t = tan

o = opposite

a = adjacent

h = hypotenuse  

cos = 2/3 where 2 is adjacent side and 3 is hypotenuse, now find opposite side using a^2 + b^2 = c^2 //c is hypotenuse side

2^2 + b^2 = 3^2

4 + b^2 = 9

b^2 = 9 - 4

b^2 = 5

b = square root (5) = 5^(1/2) //opposite side

sin = O/H

sin = \frac{\sqrt{5} }{3}

//Hope it helps.

Answer:

1. 400 2. 220 3. 300

Step-by-step explanation:

1. 701 to the nearest ten is 700 and 299 is 300 then subtract.

2. 268 rounds to 270 and 53 to 50.

3. 51 rounds to 50 and 250 stays the same.

The way you do this is by looking at the tens place and see is the number is 1,2,3,4 round down 1 number but if the number in the tens place is

5,6,7,8, or 9 you round up
