Which set of angles can be used to construct a triangle? a) 29°, 82°, and 69° b) 34°, 92°, and 58° c) 44°, 46°, and 86° d) 50°, 63°, and 62°

The correct answer is A) 29°, 82°, and 69°

Explanation:

A triangle is a polygon or shape with three sides, three vertices, and three angles. Additionally, in all triangles no matter if they are equilateral (triangles with three equal sides), scalene (triangles with three unequal sides) or isosceles (triangles with two equal sides), the angles add up to 180° and therefore, you need three angles that add up to 180° to construct a triangle. According to this, the set of angles that can be used to create a triangle are 29°, 82°, and 69° because 29 + 82 + 69 = 180° which is the total sum up of all the angles of any triangle.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
