Answer:
0.5
Step-by-step explanation:
ones . tenths hundredths thousandths
0 . 4 5 9
We are rounding the 4 so we look at the next digit, which is a 5
Since it is 5 or above, we round the 4 up
0.5
So here's a little geometry trick. Hope you're listening! So the angle is in direct correlation to the side directly opposite of it (:
that being said, 180 degrees in a triangle-70 degrees=110 degrees. so the 2 remaining angles are the same because bothopposite side lengths are 5. therefore.
2x=110
x=55 degrees (:
Answer: (√2 - √6)/4
Step-by-step explanation:
I am going to use the sum formula: sin(A + B) = sin A cos B + cos A sin B
Let's say A = 135° and B = 30°
sin(135° + 30°) = sin(135°) * cos(30°) + cos (135°) * sin(30°)
= (√2)/2 * 1/2 + (-√2)/2 * (√3)/2
= (√2)/4 + (-√6)/4
<em>= (√2 - √6)/4</em>
The answer is D.
-4,4
Hope this helps! :)
