<u>Exponents Properties</u>
We need to recall the following properties of exponents:
We are given the expression:
We need to express the following expression in terms of n.
It's necessary to modify the expression to use the given equivalence.
Recall . Thus:
Applying the property:
Substituting the given expression:
Or, equivalently:
Answer:
m∠B = 43°
b = 26.1
c = 38.3
Step-by-step explanation:
By applying triangle sum in the given triangle,
47° + 90° + m∠B = 180°
137° + m∠B = 180°
m∠B = 43°
By applying sine ratio to the angle measuring 47°.
sin(47°) =
=
c =
c = 38.28
c ≈ 38.3
By applying cosine rule,
cos(47°) =
=
=
b = 38.3[cos(47°)]
b = 26.1
