Dafna1 [17]

Answer:

60°

Step-by-step explanation:

Am equilateral triangle is a triangle that has all its sides and angles equal. Note that an equilateral triangle has 3 sides and angles.

Let the angles be a, b and c

The sum of angle in a triangle is 180°, hence;

a+b+c = 180°

Since a = b = c

The equation becomes;

a+a+a = 180°

3a = 180

a = 180/3

a = 60°

Hence the measure of the angles of an equilateral triangle is 60° for the three angles.

PERSON WHO GETS IT RIGHT GETS BRAINLIEST
saul85 [17]

Step-by-step explanation:

Let x = number of games that Alex played

The total money that he spent C is given by

C = 2x + 15

If he spent $45, then we can write

45 = 2x + 15

Solving for x, we get

2x = 45 - 15 = 30 \Rightarrow x = 15

This means that Alex played 15 games.
