When angles of a triangle adds up to 125 degrees. What is the sze of the third angle?
Its 3rd angle is 180-125 = 55 degrees
What is the measure of angle A in triangle ABC if B equals 15 degrees C equals 65 degrees and side a equals 19?
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees
What is the angle when 3 triangle angles are added together?
The 3 interior angles in any triangle add up to 180 degrees.
If an isoceles triangle has angles of 20 degreesand 80 degreees what is the measure fore third angle?
The 3rd angle is 80 degrees
What is the third angle of a right triangle if one of the angles measures Y?
If Y is the right angle then the third angle is indeterminate. Otherwise it is 90 - Y degrees.
What is the side opposite the vertex angle of an isoscles?
If you mean the vertex where the two equal sides of an isosceles triangle intersect, the side is the base.
A base angle of an isosceles triangle is 6 degrees more than the vertex angle. Find the vertex angle?
56 degrees
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 53?
If your "53" is in degrees, then the vertex angle is 74 degrees.
The exterior angle of a base angle in an isosceles triangle is 100 degrees What is the measure of the vertex angle?
20 degrees
How do you find lengths of sides of isosceles triangle if vertex angle is 15 degrees?
You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 42?
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
What is the vertex angle of an isosceles triangle if one of its base angle measures 62?
Vertex angle = 180 - 2(62) = 56 degrees
How can a triangle with a right angle also be isosceles triangle?
An isoscles triangle is a triangle which has two of its sides equal in length. Yes, absolutely a right triangle can also be an isoscles triangle.
What is the measure of the vertex angle of an isosceles triangle if the measure of one of it's base angles is 56?
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
A base angle of an isosceles triangle is 9 degrees more than the vertex angle Find the vertex angle?
let the vertex angle be x degrees, then the base angle is x + 9 degrees. Since in a triangle the sum of the angle is 180 degrees, and the base angles in an isosceles triangle are congruent, we have: x + 2(x + 9) = 180 x + 2x + 18 = 180 3x + 18 = 180 subtract 18 to both sides 3x = 162 divide by 3 to both sides x = 54 Thus the vertex angle is 54 degrees.
What is A segment that connects a vertex of a triangle to the opposite side of the triangle at a right angle?
The hypotenuse of a right angle triangle is opposite to its right angle of 90 degrees.
What is the measure of a base angle of an isosceles triangle if its vertex angle measures 65?
57.5 degrees
