1. You got it right.
4π/9 x 180/π = 80°
2. To get a coterminal angle you start with your angle and then you add or subtract 360° (one cycle around the circle).
-123+360+360 = 597°
-123-360 = -483°
3. The angle is 215° from the point (1,0) on the unit circle. The angle 215° is between 180° and 270° so it is in quadrant 3.
Answer:
YOUR ANSWER IS 9
Step-by-step explanation:
1.80/4= 0.45
2.70/6=0.45
5.40/12=0.45
0.45*20= 9$
To solve this problem we can make the following rule of three
6 ---> 3/4
x ----> 1
Clearing x we have:
x = (1/3/4) * (6)
x = (4/3) * (6)
x = 24/3
x = 8
Answer:
Carlos climbs 8 miles for every mile Lara climbs.
17 + x = 26
17 +n = 26
n + 17 = 26
something like those, you didn't give options to choose from.
