sin-1 (4/20)= 11.53 so about 12 degrees
OpenStudy (anonymous):
just plug it in the calculator
OpenStudy (anonymous):
thankyou. would you mind helping me with about 9 more questions
OpenStudy (anonymous):
sure if i can :D

are you going to ask the questions?
OpenStudy (anonymous):
ok..Find the measure of A to the nearest whole degree. Use the table for sine
OpenStudy (anonymous):
and yes
OpenStudy (anonymous):
same thing inverse sin which is sin-1(7/10)=44.43
OpenStudy (anonymous):
so it's 44 degrees

i need help like doing what i'm doing. im only in the 9th grade and ive never learned about this
OpenStudy (anonymous):
you should have a button in yous calculator that says sin-1
OpenStudy (anonymous):
you push it and then divide the opposite side of the angle by the hypotenuse
OpenStudy (anonymous):
get it?
OpenStudy (anonymous):
ok and i should get 19

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):
did you find the sin button?

above it there's a sin-1 right?
OpenStudy (anonymous):
not on mine i have the TI 84.... but when press the 2nd button and sin it says Sin-1 right
OpenStudy (anonymous):
perfect
OpenStudy (anonymous):
so click 2nd sin then put ( opposite side of A divided by the hypotenuse)
OpenStudy (anonymous):
what would that be in this equation

so sin-1(3/9)= 19
OpenStudy (anonymous):
the opposite side is the side not touching the angle and the hypotenuse is the longest side
OpenStudy (anonymous):
3/9 try it again now
OpenStudy (anonymous):
i keep getting .3271946968
OpenStudy (anonymous):
did you click sin-1(3/9)
exactly like that
sin-1(3/9)

OpenStudy (anonymous):
if it doesn't work do sin-1 .3333333333 wich is 3/9
OpenStudy (anonymous):
don't push anything between sin-1 and the (3/9)
