The 3rd angle is 80 degrees
triangle measure
Given only the information provided in the question, the answer is to measure it.
In a right angle triangle,pythagoras theorem can be used if (1)the 2 sides are equal and their measure is less than the hypotenuse (or) (2)the 2 sides are different and their measure is less than the hypotenuse.
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
Trigonometry is useful in buliding, amongst other professions and industries. Trigonometry is a branch of mathematics that deals with triangles, specifically right-angled triangles. It can be used to measure the angles of a triangle as well as all three sides, as long as two measurements are given.
You can find it by using the Pythagorean theorem if you know the side and the base of triangle. In an isosceles triangle the median is also the altitude. The formula is: (The measure of the side length)^2 - (The measure of the one half of the base length )^2 = (The measure of the altitude)^2. Find the square root of the result that you'll have the measure of the altitude.
The interior angles of a triangle add up to 180. So a triangle with 3 equal sides (or angles) will have 60-degree angles. * * * * * True, but the question is about an isosceles triangle, not an equilateral triangle. The angles of an isosceles triangle are x, x and 180-2x degree where x is a measure between 0 and 90 degrees.
If one side of an isoceles triangle has a measure of 12.1, then either... 1. One of the other sides is also 12.1. ...or... 2. The other two side as equal to each other but not equal to the known side. In both cases, the unknown side(s) are unknown, because the angles are not stated.
The 4 interior angles add up to 360 degrees
40 degres
is it a right triangle if the measure is 5 7 and 9
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
The three interior angles add up to 180°. (180° is the measure of a triangle)
There are three angles in a triangle but to measure them you would use a protractor.
it depends on the triangle
A triangle on a concave surface.
A right triangle, whose the length measure of the side opposite to the angle of 30 degrees is one half of the length measure of the hypotenuse.
