The base of an isosceles triangle is 3 cm in lenght and the angle opposite the base measure 64 degrees Find the lenght of each of the component sides?
Since the vertex angle is 64⁰, the base angle is 58⁰, (180⁰ - 64⁰ )/2.
Using the Law of Sines we have
side length/sin 58⁰ = 3 cm/sin 64⁰ (multiply by sin 58⁰ to both sides)
side length = (3 cm)(sin 58⁰)/sin 64⁰ ≈ 2.8 cm
Thus, the congruent sides of the given isosceles triangle have a length of 2.8 cm.

How many degrees in an isosceles tringle?
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
Is a isosceles triangle is a acute obtuse or right?
An isosceles triangle can be acute, obtuse, or right, depending on the measure of its angles. If all angles are less than 90 degrees, it is an acute isosceles triangle. If one angle is greater than 90 degrees, it is an obtuse isosceles triangle. If one angle is exactly 90 degrees, it is a right isosceles triangle.
What is a right isosceles?
A right isosceles triangle is a type of triangle that has two sides of equal length and one angle measuring 90 degrees. The two equal sides are often referred to as the legs, while the third side, opposite the right angle, is called the hypotenuse. In a right isosceles triangle, the angles opposite the equal sides each measure 45 degrees, making it a specific case of both isosceles and right triangles. This triangle is commonly used in various mathematical and engineering applications due to its unique properties.
How many degrees are in a icocsoles triangle?
An isosceles triangle has a total of 180 degrees, just like any triangle. In an isosceles triangle, two sides are of equal length, which means the angles opposite those sides are also equal. Therefore, if you know the measure of one of the equal angles, you can calculate the third angle by subtracting twice that angle from 180 degrees.
What is the degrees of an acute isosceles triangle?
101 degrees :p
How many degrees in an isosceles tringle?
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
How many degrees is there in an isosceles triangle?
because an isosceles triangle or any kind of triangle is 180 degrees.
Is a right triangle can be isosceles?
Yes. Only if the other two angles of the right triangle are congruent and each equal 45 degrees. Then using the isosceles triangle theorem, you know that the two sides opposite the angles are congruent.
What degree angles has an isosceles triangle?

How many degrees are in the angle of an isosceles triangle?
There is 180 degrees in every triangle.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
The triangle with angles measuring 50 degrees, 65 degrees, and 65 degrees is an isosceles triangle. In an isosceles triangle, two of the three angles are equal, making it a special type of triangle. In this case, the two angles measuring 65 degrees are equal, indicating that the two sides opposite these angles are also equal in length.
