Option A:
m∠B = 42.1°
Solution:
Given data:
b = 18, c = 15 and m∠C = 34°
Using sine formula:
Substitute the given values.
Do cross multiplication.
Divide by 15 on both sides.
Switch the sides.
m∠B = 42.1°
Option A is the correct answer.
Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is or 1/9 to the 3rd power.
<em>Down is a formula I made!</em>
Main number: 1/9
Repeating how many times: 3
Expression:
Therefore, 1/9 to the 3rd power is 1/729.
