Refer to the diagram shown below.
Given:
m∠A = 19°
c = 15
By definition,
sin A = a/c
Therefore
a = c*sin A = 15*sin(19°) = 4.8835
cos A = b/c
Therefore
b = c*cos A = 15*cos(19°) =14.1828
Answer:
The lengths are 4.88, 14.18, and 15.00 (nearest hundredth)
Answer:
Your answer to this would be 114.44
It was 114.435, but I round it.
D to B =180
B to D=180
D to C =19
The answer is x=7. I hope this helps. Tell me if you need an explanation!
