Well how many 12's are in 24 (forget the negative sing for a moment). Two right? Well that means multiply 4 by 2 and get 8, but where does that negative sign go? Just add it! It makes it so much easier taking it away and then putting it back. That is a trick for this problem. y=-8 while x=-24 Hoped I helped!

Make Length the subject
Factorize the numerator
Answer:
A. 7:21 = 3:9
Step-by-step explanation:
7 is to 21 as 3 is to 9.
Replace the word to with colons and the word as with the equals sign
7:21 = 3:9
So, first you must find the remaining angle measure. To do this add 25 and 90 then subtract from 180. The remaining angle measure is 65 degrees.
Next, use tangent, cosine, or sine to find the remaining side lengths.
I used sine of 25 which is opposite of hypo. which is sine 25 = y/43.
Multiply both side by 43 and you get y=18.17
Do the same to find x, but use the sine of 65, and you get sine 65 = x/43.
Multiply both sides by 43 and you get x=38.97
Hope this helped!
