YEs your ans is exactly right..its 3rd option...as you marked..
OpenStudy (anonymous):
If the sin 45° is 0.707, then the cos _____° is 0.707.
I put 45
OpenStudy (anonymous):
@zaibali.qasmi
OpenStudy (anonymous):
still cos45 is 0.707..both have same value at angle 45
OpenStudy (anonymous):
yes you use right putting

your ans is right its hypt/opposit
OpenStudy (anonymous):
If sin y° = 9 divided by c. and tan y° = 9 divided by d. ,what is the value of cos y°?
OpenStudy (anonymous):
cos y° = 9c
cos y°=c divided by d.
cos y°=d divided by c. <--- my answer
cos y° = 9d

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)
OpenStudy (anonymous):
I didn't understand this one?
OpenStudy (anonymous):
ans sin y=perp/hypt=4/20=0.2=>y=sin^-1(0.2)=11.53 nearly approches to 12
OpenStudy (anonymous):
so its 12 ?

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)
OpenStudy (anonymous):
This one i didn't get it
OpenStudy (anonymous):
1st find the remaing side length using phythagoras thorem and then use relation os SIN X=PERP/HYPT you will get ans..
OpenStudy (anonymous):
I still don't get it
