Answer:

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : \frac{sin 42}{a} = \frac{sin 55}{175} ⇔ a = sin42 \frac{175}{sin 55} ⇔ a= 142.95

Parte3 :

Using the same law : c = sin 83\frac{a}{sin 42}  or  c= sin 83\frac{175}{sin 55}  ⇔ c= 212.04

Eduardwww [97]

Answer:

see below

Step-by-step explanation:

Because the sum of all angles in a quadrilateral is 360° we have:

Tuning Guitars How do you know if a guitar has been tuned accurately? The units on a guitar tuner are measured in cents. The uni
natali 33 [55]

The question is an illustration of units and measurements

<em>The question is incomplete, as the measurement of the guitar is not given; so, I will provide a general explanation.</em>

<em />

From the question, we understand that:

The closer the measurement is to 0, the more accurate it is.

This means that:

  • A measurement of 1 cent is more accurate than a measurement of 1.5 cent, <em>because 1 is closer to 0</em>
  • A measurement of -2 cent is more accurate than a measurement of 2.5 cent, <em>because -2 is closer to 0</em>

So, all you need to do is:

  • Get both measurements
  • Compare them, as to <em>which is closer to 0</em>
  • The measurement that is closer to 0, is the most accurate
