Find the exact value of sin-1 the quantity square root of three divided by two
1 answer:
Answer:
Answer is 60 degrees.
Step-by-step explanation:
We know that in a right angled triangle if one leg is 1, and hypotenuse is 2,
then other leg = 
(By using Pythagorean theotrem)
Now consider a right angle triangle with hypotenuse 2 and one leg 1, and the angle between other leg and hypotenuse.
Since sin 30 = 1/2 we have cos 60= sin (90-60) = 1/2
Hence sin 60 = rt 3 /2
Using the above we get sin inverse of quantity square root of three divided by two is 60 degrees.

I believe that x and y are == given that both sides are 24:24
so we know a triangle must add up to 180 degrees
just do 180-46 = 134
134/2=67
x=y=67
The answer is B. -4
You can simply count the blocks
So for every one block over on the x-axis it goes 4 blocks down on the y axis

Answer:
None of the above.........
You will need 46.08 grams.
48 • 0.04 (4%) = 1.92
multiply 48 by 0.04 to find what 4% of 48g is
48 - 1.92 = 46.08
then subtract the 4% to get the rest amount
