Answer:
Step-by-step explanation:
= 12 - 3
= 9
= -8 - 4
= -12
= -60 + 12
= -48
= -2 + 2
= 0
= 17
= 1
Answer:
2 5 /14
Step-by-step explanation:
−10 2/7 ÷ (−4 4/11)
Change to improper fractions
−10 2/7 = - (7* 10+2)/7 =-72/7
-4 4/11 = -( 11*4+4) = -48/11
-72/7 ÷ -48/11
Copy dot flip
-72/7 * -11/48
Canceling an 8 from the top left and the bottom right
-9/7 * -11/6
Canceling a 3 from the top left and the bottom right
-3/7 * -11/2
33/14
Now we change it back to a mixed number
14 goes into 33 2 times 2*14 = 28
33-28 = 5 this goes over the denominator
2 5 /14
Yes use inverse to get the correct answer
Your are right,
and 2
are solutions.
Of course each of these solutions can be replaced by the same number +k2
(with k being an element of Z) since sin x=sin (x+k2
) with k being an element of Z.
Those are angle measures expressed in radians.
If you translate in degrees you basically have to know that
radian=180 degrees
so
radian=60 degrees and 2
=120 degrees. So this two could be values of theta (A and B).
On top of that
could also be a solution (x+k2
with k=1). This can be translated to 60+360=420 degrees which is solution D.
So C. 240 degrees is the only one that could not be a value of theta.
