Answer:
3. 108.982 feet per second
so yes faster than 100 feet per second
4.
5. 46.336°
6. 31.999°
7. 73.301°
8. 18.435°
Step-by-step explanation:
3. tan(16)= 250/x
x=250/tan(16)
x= 871.853611
speed=871.853611/8
= 108.982 feet per second
so yes faster than 100 feet per second
4. I do not understand the formulation of the question
5. sinx= 3.4/4.7
asin*(to the power of -1)*(3.4/4.7)=x
x=46.336
6.tanx=4,532/7253
atan*(power -1)* (4,532/7253)=x
x=31.999
7.tanx=500/150
x=73.301
8. tanx=30/10
atan(30/10)=x
x=71.56505118
90-71.56505118=18.43494882(the final angle)
