the 15 is on the long side and the 22 is where you put the x
i dont know how to do that
OH WHOOPS HOLD ON, let me draw the diagram again
the 22 is where you put the x
nope, "base angle" means the angle on the bottom
"altitude" is the height of the triangle
anyway, sin(22) = opposite/hypotenuse = x/15 solve for x
f 13.9 g 9.0 h 5.6 j 6.1 these are the awncer choices
alright, we know that sin(22) = x/15, so what is x?
um how do i do that ?
hint: a = b/c b = c*a
so do i use a calculator
now look at what I wrote before: sin(22) = x/15
what do i put into the calculator
I'm trying to help you figure it out on your own let's try an easier problem: 2 = x/4, what is x?
idk i never learned sin and that stuff because i was new to the school and they already tought that
let's ignore the sin stuff for now, just solve this problem: 2 = x/4 if x divided by 4 is 2, then what is x?
no, please try again
what number gives you 2 when you divide it by 4?
what is 8 divided by 4?
great! so, what number gives you 2 when you divide it by 4?
excellent! so, if 2 = x/4, then x = 8, because 8 divided by 4 is 2
in order to find x, we multiplied 2*4
so, back to the sin stuff if sin(22) = x/15, we can find x by multiplying sin(22) and 15 so what is x?
so would i do something like that to get my awncer to the first question
yup! so, if sin(22) = x/15, what is x?
what two numbers do you need to multiply to get x?
15 and 22 ?
not quite what is on the left side of the equation?
no, the whole thing
great! so, what do you multiply to get x?
no, please think again
yes! so, what do you multiply to get x?
you need to multiply TWO things, what's the other number?
YES!, sin(22) and 15!
x = sin(22) times 15
and that gives me 5.6
excellent work, you're done
thank you so much !!!!!
