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)
It is which ever one adds up to 90
Answer: 21,952 cm³
Explanation:
Volume = 28 x 28 x 28 = 29 152 cm³
10*0.25=2.5
2.5/10*100=25 lbs
25-10=15 lbs
