Answer:

A. 1,2,3

Step-by-step explanation:

The only Pythagorean triple that is an arithmetic sequence is 3, 4, 5 and its multiples.

The triple 1, 2, 3 is not a Pythagorean triple. (It doesn't even form a triangle.)

_____

If you don't recognize the offered choices as being among the Pythagorean triples you have memorized, you can always check to see if ...

a² +b² = c²

1² +2² = 1 +4 = 5 ≠ 3² . . . . . (1, 2, 3) is not a Pythagorean triple

3² +4² = 9 +16 = 25 = 5²

5² +12² = 25 +144 = 169 = 13²

7² +24² = 49 +576 = 625 = 25²

A couple of other triples commonly seen are ...

(8, 15, 17), (9, 40, 41)

Central Allen High School's girls golf team has won 76% of its games this year. The team has won 19 games. How many total games

lawyer [7]

Answer: 25 games

Step-by-step explanation:

Take the fractions 76/100 and 19/x

Cross multiply. 76 times x equally 76x and 100 times 19 equals 1900.

Divide 76x by 76 which equals just x.

Divide 1900 by 76 which equals 25.

x=25

Equiangular polygon has how many sides exterior angle is 25

Softa [21]

If the exterior angle is 25o then the interior angle is its supplement.
The interior angle = 180 - 25 = 155 degrees. All angles are equal in the interior.
The sides aren't.

I'm hoping you get an answer besides mine. I can take you so far.
The formula for an interior angle is

180(1 - 2/n) = Interior angle. When you solve this you get
180(1 - 2/n) = 155
1 - 2/n = 155/180
1 - 2/n = 0.86111111
- 2/n = 0.8611111 - 1
2/n = 0.13888888
2 / 0,1388888 = n
n = 14.4

You can google equiangular polygon theorem to see where I got the formula. The problem is that I really don't know how to interpret the answer. It looks like you have 14 conguent sides and 1 that is 0.4 left over. The figure might still be equiangular.
