Answer:
s2 = 19 a=19 u1= 19√2 (26.87) u2= 19√2 (26.87)
Step-by-step explanation:
s2 - subtrace s1 from h to get 19
a - use the geometric mean of s1 and s2 (squre root of 19 times 19)
u1 and u2 - pythagorean thm
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.
