For an equilateral triangle, side A actions
Explanation:
First you must recognize that for an it is provided triangle, every 3 sides have equal lengths.
You are watching: What is the angle of an equilateral triangle
This means you can set the 2 values because that Side A and Side B equal to one another, because they measure up the very same length, to settle for
You now understand that
So the length of next A (and side B for the matter) is 8.
One angle of an it is intended triangle is 60 degrees. One side of that triangle is 12 centimeters. What are the procedures of the two other angles and also two various other sides?
Explanation:
An it is provided triangle is one in i m sorry all 3 sides room congruent. It additionally has the home that all three internal angles room equal. In other words, all three angles that an equilateral triangle are constantly 60°. Since all sides room congruent, the other two sides both measure up 12 centimeters.
Explanation:
To discover the perimeter of an it is provided triangle, we will use the adhering to formula:
where a is the size of any kind of side of the triangle. Because an equilateral triangle has 3 equal sides, we deserve to use any side in the formula. To uncover the length of one side of the triangle, we will solve for a.
Now, we understand the perimeter that the it is intended triangle is 18in. So, we will substitute.
Therefore, the length of one side of the it is intended triangle is 6in.
Explanation:
An equilateral triangle has 3 same sides. So, to find the size of one side, we will use what us know. We understand the perimeter that the it is provided triangle is 39in. So, we will certainly look at the formula because that perimeter. Us get
where a is the length of one next of the triangle. So, to discover the length of one side, us will settle for a. Now, as proclaimed before, we know the perimeter that the triangle is 39in. So, we will substitute and solve because that a. We get
Therefore, the size of one next of the equilateral triangle is 13in.

An equilateral triangle is inscribed within a one of radius 8. Offer its area.
Possible Answers:
Correct answer:
Explanation:
The cheat is to recognize that the circumscribed circle, or the circumcircle, has as its facility the intersection the the 3 altitudes that the triangle, and that this center, or circumcenter, divides every altitude right into two segments, one twice the size of the other - the longer one gift a radius. Due to the fact that of this, we have the right to construct the following:
