Sin(x) = base / hypotenuse
sin(x) = 7/9
x = arcsin(7/9)
x = 51 degrees
i dont know my friend so try asking someone better than cause i have no brain for this type of math
Answer:
y= -2x+15
Step-by-step explanation:
AB=6 but DE=2(AB) so DE=2(6)=12
I’m guessing
Answer: x(.25)+(4+x(.25))=y
Step-by-step explanation:
1. set up the equation-
Ali has an unknown amount of quarters so make that x.
We know quarters are 25 cents so .25 if he has one quarter you put that one quarter into x, 2 into x and so on
Tom has 4 more, since he has 4 more it is 4+x and one again times .25
2. that is it
