Answer:
units
Step-by-step explanation:
Considering an equilateral triangle, the measure of the angles are 60ᵒ each and the sides have equal length of 2 units. If the equilateral triangle is divided into two equal right triangles, we have angles 30ᵒ, 60ᵒ and a right angle.
Let the value of the side opposite 60ᵒ angle be represented by x., the side opposite the right angle is 2 units, and that opposite the 30ᵒ is 1 unit.
Applying the Pythagoras theorem to determine the unknown side of the triangle, we have;
= +
= +
4 = + 1
= 4 - 1
= 3
⇒ x =
The length of the side opposite 60ᵒ angle is units.
If you use the 20% off coupon your total will be $16.80.
+ Purchase Price = $21
- Discount (21 x 20)/100 = $4.20
<span>= Final Price 21 - 4.20 = $16.80
</span>
If you use the $5 dollars off coupon your total will be $16.00.
$21 - $5 = $16.00
The better coupon to use would be the five dollars off coupon because $5 dollars off will be 80 cents less than using the 20% coupon.
