o
cos(8) =
sin() = -1
o 8
IN
The measure of the reference angle is 30°.
tan(0)
= -V3
O The measure of the reference angle is 45º.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

my dear correct answer is option number 3

110

step-by-step explanation:

based on the question i am guessing that it is a typo for abc

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
