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.

i am thinking c. sorry if im wrong .

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
