How do you find the missing angles of a triangle with one?
you must know more information. Like the lengths of 2 sides. Then using Trig (law of sines or law of cosines) you can find the remaining sides and angles.
How do find the sum of the angles in a quadrangle with each side different lengths not using a protractor?
The sum of the angles in a quadrangle is 360 degrees, whatever the side lengths.
How do you find the measure of a triangle with 3 different measures?
Too broad of a question... What measure are you talking about? angles? side lengths?
How do you find the perimeter of an obtuse triangle using the angles?
measure with an protacter
Are trigonometric functions used to find the acute angles of a right triangle?
they can be, depending on the information that you are given. If you know lengths of sides, then YES.
How can you use ratios of the side lengths to find the angle measures of the acute angles in a right triangle?
By using trigonometry that is applicable to a right angle triangle.

How do you find the width of a triangle with 3 angles and 2 lenghts?
Any one of the lengths can be taken as the width.
How do you find the ratio of two adjacent side lengths in a triangle?
They are in the same proportion as the sines of the angles that are opposite them.
How do you find the reference angles for cos?
by using rightangle triangle
How do find the sum of the angles in a quadrangle with each side different lengths not using a protractor?
The sum of the angles in a quadrangle is 360 degrees, whatever the side lengths.
How did thy come up with cosine law?
Because it helped find angles in a triangle when only the side lengths were known.

How do you find the perimeter of an obtuse triangle using the angles?
measure with an protacter
How do you find the short leg of a right triangle?
The answer depends on what information you do have about the triangle: the lengths of the other two sides, or the hypotenuse (longest side) and one of the acute angles, or the other leg and one of the acute angles, etc.
How do you find which triangle if you know the lengths of the sides of a triangle whether it is isosceles or equilateral or scalene?
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
