Per recent schools question and answer requested students to say what they think is the main important aspect for a student to do in order to gain success. The one that response stood out from the rest was practice. Persons who commonly successful do not become successful by being born. They work hard and persistence their lives to succeeding. This is how you can achieve your goals. down below are one of the answer and question example that you might possibly work with to practice and improve your information and also give you insights that will assist you to sustain your study in school.

## Question:

Find the value of x. Round to the nearest degree. show your work.

## Answer:

To solve such questions we need to know about **trigonometric ratios.**

## Trigonometric functions

where perpendicular is the side of the **triangle **which is opposite to the angle, and the **hypotenuse **is the longest side of the triangle which is opposite to the 90° angle.

The value of **x **is **51.075°.**

## Explanation

Given to us,

- AB = 7
**units,** - AC = 9
**units,**

We know for a** right-angled triangle**, sinθ is given as,

where,

**θ **is the **angle,**

Perpendicular is the side **opposite **to the** **angle**,**

the **hypotenuse** is the **longest **side of the triangle and it is** **always opposite to the right angle.

### In **ΔABC,** for **∠x,**

- Perpendicular = AB = 7 units,
- hypotenuse = AC = 9 units,

substituting the values into the formula for Sin(x),

,

Hence, the **value **of x is **51.075°.**

From the answer and question examples above, hopefully, they could simply help the student solve the question they had been looking for and keep in mind of most things declared in the answer above. You would certainly then have a discussion with your classmate and continue the school learning by studying the problem alogside each other.
