Answer:
22.470
Step-by-step explanation:
In this example you have to use the trigonometric function sine which is defined as 
Plug in known values:
Multiply both sides by 25
Approximate sin(64) using a calculator:
Simplify
Step-by-step explanation:
Sn=n/2(2a+(n-1)d). n=20
S20= 20/2 (2x5+(20-1)3 a=5
S20=10(10+57). d=8-5=3
S20=10x67
S20= 670
Hope this helps you
have a great day
Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since t<span>he straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function
