Can someone smart help me with this question plz:)

By the way the select is complementary or congruent

The angles of an equilateral triangle are congruent. Let the measure of each angle be xx. Then, by the Triangle Sum Theorem, x + x + x = 3x = 180 degrees. Solving for x gives x = 60 degrees.

Step-by-step explanation:

An equilateral triangle is a triangle with 3 congruent sides, and if the sides are all congruent, that also makes the angles congruent to one another. So to find out what each angle measurement would be, all you would do is divide 180 by 3, giving you a total of 60.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
