Notice the picture
we have, the opposite side
the angle
and we want the hypotenuse
so recall your SOH CAH TOA
which one has all that? low and behold, is Ms Sine,
so let's bother Ms Sine
make sure your calculator is in Degree mode, since the angle here is in degrees, as opposed to Radian mode
<span>CD = 24
Triangles ABX and CDX are similar triangles. So the ratio of lengths between corresponding legs of the triangles will have the same value. You know that they're similar triangles because both of them are right triangles (so you know that one angle is the same in both) and that arc draw on both angles AXB and CXD indicate that those angles match as well. That tells you there's a second angle that's matching in both triangles, and because two of the angles match, you also know that the unmarked angle matches as well since all the angles in a triangle have to add up to 180 degrees.
So you know that AB/CD = BX/DX. Substitute known values and you get
AB/CD = BX/DX
12/CD = 2.5/5
Now solve for CD
12/CD = 2.5/5
12/CD = 1/2
24/CD = 1
24 = 1 * CD
24 = CD
So the value of CD is 24.</span>
How many friends are there
Answer:
the answer would be C.
Step-by-step explanation:
You add up 4 + 5 which is Sam and RJ together. Then multiply 5 to get the amount they sold for each.
Hope this helped!
