Explain the difference between using the sine ratio to solve for a missing angle in a right triangle versus using the cosecant r
oksano4ka [1.4K]

Answer:

The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.

To find a missing angle using sine, you would need to use the inverse of sine. For example,  if the sine was  \frac{30}{40}, to find the angle you would need to find sin⁻¹ of  \frac{30}{40} which is x =  sin⁻¹ (0.75). Therefore x equals approximately 49°.

What percentage is 142-58
Misha Larkins [42]

SOLUTION:

Step 1 :

In this question, we are meant to find what percent of 142 is 58.

Step 2 :

We make the assumption that 142 is 100 % since it is our output value.

Step 3:

We next represent the value we see with x.

Step 4 :

From step 2, it follows that 100 % = 142.

Step 5 :

In the same vein, x % = 58.

Step 6 :

This gives us a pair of simple equations:

\begin{gathered} 100\text{ \% = 142 ---- equ 1} \\ x\text{ \% = 58 }\ldots\ldots\ldots\ldots\text{ equ 2} \end{gathered}

Step 7 :

By simply dividing equation 1 by equation 2 and

taking note of the fact that the Left-Hand Side of both equations have the same unit ( % ), we have that :

\frac{100\text{ \%}}{x\text{ \%}}\text{ = }\frac{142}{58}

Step 8 :

Taking the inverse ( or reciprocal ) of both sides yields:

\frac{x\text{ \%}}{100\text{ \%}}\text{ = }\frac{58}{142}\begin{gathered} x\text{ = }\frac{58\text{ x 100}}{142} \\ \text{x = }\frac{5800}{142} \\ x\text{ = 40.85\%} \end{gathered}

CONCLUSION:

Therefore, 58 is 40.85 % of 142.

Eq 1. Y = x + 14

According to 2nd condition

Eq2. (Y+3)= 3(x+3)

Put value of y in eq 2,,,,,,,, x = 4

Put value of x in eq 1. ,,,,,,,,, y = 18
