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.

Answer:
20%
Step-by-step explanation:
We were given a price at $50 on sale for $40. To get the markdown percentage, take the amount of money you've discounted the merchandise at and divide it by the sales price.
$50 sweaters, you can put them on sale for $40.
The difference between these two prices is $10.
Now, we need to add the amount of which it was marked down
Therefore, the watch has been marked down by 20%.
