Option 1
Jessica can make 2 scarves
yes, because the quotient of
<u>Solution:</u>
Given, Jessica used yard of fabric to make a scarf.
We have to find can she make 2 of these scarves with yards of fabric, and why?
Now, let us find number of scarves that can be made from available scarf
We know that,
so we can make 2 scarves.
Hence, yes, we can make 2 scarves because quotient of
So 1st option is correct
Answer:
Step-by-step explanation:
I will show you by example. For the sin ratio, we have that the sin of the reference angle is equal to the side opposite the angle over the hypotenuse of the right triangle. We use this example for finding the ratio, knowing the angle:
found on your calculator. Because this is a special angle in a right triangle, we can also say, by looking at a 60 degree reference angle that the side across from the angle measures square root of 3, and the hypotenuse measures 2. So in terms of a radical,
If we don't know the angle, we use the 2nd button on our calculator to find it. For example, if our problem looked like this:
,
we are asked what angle has a sin ratio of 1/2. We find this angle by pressing the 2nd button on our calculator, then the sin button and you will see this on your screen:
Enter either a .5 or a 1/2 after that open parenthesis and hit enter and you'll get the angle measure. That's how you use the inverses to solve for missing angles.
