Answer:
1, √3 , 2
Step-by-step explanation:
Note the side values of a 30-60-90 triangle. The answer is 1, √3 , 2, with 1 being the shortest side, and 2 being the hypotenuse.
For example:
10 , 10√3 , 20 can be the side measurements of a triangle.

The number of bags of grass seed that are needed to seed the new rectangular lawn is approximately 19 bags .
<h3>Perimeter of a rectangle</h3>
The perimeter of a rectangle is the sum of the whole sides of the rectangle.
Therefore,
perimeter of the rectangle = 298 ft
The width is 67 ft.
Hence
perimeter of rectangle = 2(l + w)
where
Therefore,
298 = 2 ( l + 67)
298 = 2l + 134
298 - 134 = 2l
164 = 2l
l = 164 / 2
l = 82 ft
Therefore,
area of the rectangle = 82 × 67 = 5494 ft²
285 ft² = 1 bag of grass seed
5494 ft² = ?
cross multiply
number of bag of grass seed to fill the new rectangular lawn = 5494 / 285
number of bag of grass seed to fill the new rectangular lawn = 19.2771929825

12 cm, use the pythagorean theorem: a^2+b^2=c^2
9^2+b^2=15^2
81+b^2=225
b^2=144
b=12

Answer:
15%
Step-by-step explanation:
First, let's find how many pounds the dog's weight increased by during the year.
80 - 64 = 16
Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).
• 100 = 0.25 • 100 = 25%
The answer is A because it shows all of the terms
