Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
Answer:
98 °
Step-by-step explanation:
We know that the sum of the angles in a triangle is 180. We also know that angle DAB is 122°, meaning that angle CAB is 180-122, which is 58°. We also know that angle CBA is 24 degrees. Therefore, angle x is just 180-(58+24), which is 98
Answer:
Angle = 45
Step-by-step explanation:
It is half of a right angle also (x = 15) :)
<u><em>hi there user! Looks like your looking for help, so Mizuki came here to help you!</em></u>
the answer is:
<em>m is 2/3</em>
The whole work I did:
m + 4 ÷ 3 = 2
m + 4/3 = 2
m + 4/3 - 4/3 = 2 - 4/3
m = 6/3 - 4/3
m = 2/3
Anyways hope this helped! qwq
