Answer:
AB = 25.13
Step-by-step explanation:
X= the angle of the corner B
tan X = 10/5
tan X = 2
X = 63.43°
cos 63.43° = 10/BC
0.447 = 10/BC
BC = 10/0.447
BC = 22.37
sin 63.43° = 22.37/AB
0.89 = 22.37/AB
AB = 22.37/0.89
AB = 25.13
Answer:
50 ?
Step-by-step explanation:
You didn't give any detail about how many beads it takes to make one bracelet
Answer is 30
Multiply top of bottom of each fraction to get 30 on the bottom
So 2m/5•6 and 2m/6•5
Answer:
Step-by-step explanation:
The first two are incorrect. Only very special n's will work. (Every 10th one for n>0)
Just call A and B incorrect.
400o = 360 + 40
The answer is between C and D
The question is will a negative value for n work? Suppose n = - 1 That means you go around the circle clockwise 1 time and though the question does not say it, you must start at the positive x axis.
Having said that 40 is plus.
The 360 starts at the + x axis. It doesn't matter how it got there. 40 degrees from the +x axis is in the first quadrant. It always will be.
D is correct but C is the better answer because it includes D.
