Well we know that sin(angle) = opposite/hypotenuse. using the angle of 38 degrees we see that the opposite is 24 and the hypotenuse is x. So we fill in equation:
sin (38) = 24/x
x *sin (38) = 24
x = 24/ sin (38)
x = 38.98
x = 39.0
I think it’s 7,3 because u go side ways then go down!
5x<=8
5x is the product of an unknown number and 5 and that could be less than or equal to 8. It should be the symbol that is on top of each other but I can't type that here.
Hope that helps.
-3x - 3.2 no
-1.2-8 no
-1.2x-3.2 yes
-1.2x+3.2 no
