Use the Law of Sines to solve the triangle. Round your answers to two decimal places.
iris [78.8K]

Answer: 37.1

Explanation: The Law of sines states that there is a proportionality between a side of triangle and its correspondent angle, i.e.:

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

where:

a, b and c are sides

A, B and C are angles

In the question, there is a triangle with 27.4 as a measure of side a, angles A and C. So, it wants the side c:

\frac{a}{sinA} = \frac{c}{sinC}

\frac{27.4}{sin(99.7)} = \frac{c}{sin(20.4)}

c = \frac{27.4.sin(20.4)}{sin(99.7)}

c = 37.1

The side c is 37.1

QveST [7]

Answer:

By definition, <u>multiprocessing</u> refers to the processing of multiple processes at the same time by multiple CPUs.

By definition, <u>multiprogramming</u> keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.

The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.
