1 answer:
There are buttons on all scientific calculators for inverse trig functions.
Usually denoted as "arcsin, arccos" or with a little -1 inverse sign like this:
You put in the measurement and it gives back the angle. I
angle x = 15°
complimentary angles add up to 90° so the angle that's complimentary is 90-15 = 75°

Given:
Daniel has a set off green,blue and red.
The red marbles make up exactly half of the set.
The set has 2 blue marbles.
The green marbles in set are as twice of the blue marbles in set.
Now, to find the number of marbles in Daniel's set.
Let the number of marbles in Daniel set be
So, the red marbles =
Blue marbles = 2.
And the green marbles =
According to question:
<em>Multiplying both sides by 2 we get:</em>
<em /><em />
<em>Subtracting both sides by </em><em> we get:</em>
Therefore, there are 12 marbles in Daniel's set.
