Answer:
<2 is 50º
Step-by-step explanation:
you first want to find what x is, so you would put the two equations in an (equation)=(equation) and get x and the number across from each other, that would be x=15º. you then plug in the 15 to the equation, and solve that, resulting in 130º. The angle is going to be 180 in total, so subtract the 130º from 180º and you would get 50º
Answer:
5
Step-by-step explanation:
100= 75 + x2
x=5
The answer is the second one
Answer:
About 5.93412 radians.
Step-by-step explanation:
To calculate it you would multiply 340 by π/180 because if graphed, 340 degrees is located in the first quadrant.
I hope this helps! :)
Answer:
cos(400)
Step-by-step explanation:
Useful things:
Cofunction identity: sin(x)=cos(90-x)
Sine and cosine have period of 360 degrees.
So sin(50)=cos(40) by cofunction identity.
Since cosine has period of 360 degrees then cos(40)=cos(360+40).
That simplifies to cos(400).
