Answer
Step-by-step explanation:
Law of sines: SinB/15 = SinA/BC
B = 90
A = 180-90-21=69°
BC= (15*SinA)/SinB = (15*sin69)/1 ≈ 14m
Answer:

Step-by-step explanation:
For simplifying expressions of this sort, there are four rules of exponents that come into play;

I find it convenient to eliminate the fractions by adding the exponents, then rewrite any negative exponents as denominator factors.

Adding integers with different signs is just like adding or subtracting. First you just have to add all negative integers and also add all positive. After that positive intergers will be deducted by the sum of negative integers
The answer is
26 degrees
