In this figure, sin(a) = 2 3 What is the value of cos(b) ? A) 1 3 B) 2 3 C) 2 3 D) 3 2


\frac{2}{3}

The angles a and b sum to 90°, so they are complementary. A trigonometric identity asserts that cos(90° - a) = sin (a) for any angle a, so cos(b) = sin (a) = \frac{2}{3}.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
