Answer:
(a) 
(b) We use the property of exponent that when there is multiplication of two function then there exponent are added
Step-by-step explanation:
We have given expression

(a) We have to find the value of a
We know the property of exponent that when there is multiplication of two function then there is addition of exponent
So 


(b) We use the property of exponent that when there is multiplication of two function then there exponent are added
Answer:
EF = 3.43
Step-by-step explanation:
Sin θ = opposite / hypotenuse
Sin 26 = EF / 4.5
0.762 × 4.5 = EF
EF = 3.43
5028ft distance in the altitude between the top and bottom
