Where is the Image I might can Help
sum of triangle angles = 180
so
? = 180 - 36 - 92 = 52° => D
Answer:
D. 7 to 3
6+1=7 parts yellow, and the blue didn't change amount, so 7 parts yellow, and 3 blue.
Answer:
C = 34 degrees, A=8.6 feet
Step-by-step explanation:
Use sine law:

![sin^{-1} [12(\frac{sin122}{18})]= C](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%20%5B12%28%5Cfrac%7Bsin122%7D%7B18%7D%29%5D%3D%20%20C)
C = 34 degrees
Now that you have the C and B degrees, solve for A degrees
180 - 34 - 122 = 24 degrees for angle A
Same way as above use sine law to find the side for a now:

A=8.6 feet
** Thing to note is that you can rearrage the sine formula to have either the legnth or the angle on top. It's pretty straightforward, find the angles you do have and then work from there. If sine law doesnt work with your example, use cosine law. and work backwards. Wish you luck.
The area would be 324 yards square. Since the height is already found, you multiply 15 by 21 2/3 yards.
Hope this helped :)
