Answer:
x = 111°
Step-by-step explanation:
180 x (7 - 1) - (120 + 158 + 126 + 125 + 121 + 139) =
900 - 789 = 111
One) One millivolt is one thousandths of a volt.
Two) One megagram is one million grams.
Since there should be 180 in a tringle the bottom triangle woul be 65 65 50. assuming that the lines / and \ are the same in both traingles that means that at intersection they create the same angles above=below and left=right meaning the answer to x is x=50
Answer:
Step-by-step explanation:
use the formula { a couple of times} cos 2 Θ = 2 cos ² Θ - 1 = 1 - 2 sin ² Θ....your answer will likely have a cos 2x , a cos 4x , and a cos 6x in it.....note : cos ² Θ - sin ²Φ = cos ( Θ + Φ) cos (Θ - Φ) will also be needed for appropriate choices of Θ & Φ in terms of x
