The correct answer is -3. You just plug 7 into the equation and solve for y
The original price is $199.94
Given:
Discounted price = 159.95
Discount rate = 20%
If the discount rate is 20%, then the price is equivalent to 80%.
To get the original price, simply divide the discount price by its corresponding percentage.
Original price = 159.95 ÷ 80% = 199.94
To check
199.94 * 20% = 39.99 * value of the discount
199.94 - 39.99 = 159.95 *discounted price
Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : <span>Two triangles are </span><span>congruent if </span>"<span>ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle</span><span>.</span>"
It’s definitely B I believe
