Note!!!! ignore the S at the end these are the questions 1. side AC= 31 cm, side BC= 20 cm and angle B= 58 degrees 2. side AC= 21 cm, side BC= 28 cm and side AB= 32 cm 3. side AC= 8 cm and side AB= 10 cm please help last 3 questions of my homework. My teacher collects it =(
If two angles of a triangle each measure 55 what is the measure of the third angle?
100.
angle with smallest measure - apex
50 degrees
If that is the angles of a triangle then the 3rd angle is 110 degrees
You can't calculate any angle if all you know is one side of the triangle.
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
angle with the greatest measure
it depends on the triangle
If two angles of a triangle each measure 55 what is the measure of the third angle?
The missing angle measure is 100 degrees.
55°
Two angles of a triangle add up to 65°. What is the measure of the third angle?
It is a right angle triangle and the 3rd angle will measure 30 degrees
