2. The measure of the reference angle is 60°.
3. The measure of the reference angle is 45°
4. The measure of the reference angle is 30°.
5. tan(0) = 1
6. sin(0) = 1/2

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

if you was gonna solve for a, a is a   < -12
