stepan [7]

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.

How many solutions can be found for this set of linear equationsy=7(x+2)y=7x+14
Bogdan [553]

Answer:

Infinite solutions

Step-by-step explanation:

The two equations are the same, so therefore, any value of x will result in an output that belongs to both lines, if you understand what I mean.

Hope this helps :)

there are 90 students in grade 5, and 10% of them were absent today. in grade 6, 15% of the 80 students were absnet today. what
soldi70 [24.7K]
There would be 81 in grade 5
and 68 in grade 6

because 10% of 90 is 9 so 90 - 9 =81

and 15% of 80 is 12 so 80 - 12 = 68
