In triangle abc, a = 18.2, ∠b = 62°, and ∠c = 48°. find b 15

Measurement of side b = 17.1

Step-by-step explanation:

In a given triangle ABC, it is given a = 18.2, ∠B = 62° and ∠C = 48° and we have to find the measurement of b.

Now by Sine Rule

Here ∠C and ∠B are given so we can get the measurement of ∠A.

∠A + ∠B + ∠C = 180°

∠A + 62 + 48 = 180

∠A = 180 - 110 = 70°

Now we put these values in the sine rule.

Therefore measurement of side b will be 17.1

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
