2cosx=2sin2x. Sin2x is an identity for 2sinxcos. So 2[2sinxcosx] gives you 4sinxcosx. 2cosx=4sinxcosx. Divide 2cosx on both sides and gives you 2sinx=0 and divide again, sinx=0. Sinx is 0 at 0 and 360 degrees, or pi and 2pi. So thats what x would be. 0,360,pi,2pi.
Answer:
I'm about 3 months haha, but I'll still help you out. Angle E is equal to 75 degrees.
Step-by-step explanation:
The way to solve it is to put the 154 on top of 35 and multiply it to get the answer, 154 times 35 = 5390
A function is "a expression or equation involving one or more variables".
For example:
(x² + 7a) is a function.

Answer:
JM
Step-by-step explanation:
A tangent line is a line that only intersects a circle at one point.
LG and CJ are not lines, and GH intersects the circle twice (at point G and point H), so JM is the tangent line.
