In addition to the trigonometric ratios, what other methods can be used to solve a right triangle? Give situations for when you
might want to use them.
1 answer:
Phytagoras formulas is another method to solve right-angled triangle problem-related.
The formula is given by
where c is the hypotenuse of the triangle.
We use Pythagoras formula when we know at least the length of two sides of right angle triangle and we are looking for the length of the third side.
We use trigonometry ratio when we know the length of one side of a right-angled triangle and the size of one acute angle. We can either find the length sides or an angle using trigonometry ratio.

Step-by-step explanation:
<em>I think you have forgotten to attach the question. </em>
<em>Anyways....</em>
In order to find the area of a circle use the formula:
π Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π ×
Since you have taken pi as 3.142...
3.142 ×
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3
