How do you calculate missing angles when only given one angle and two lengths?

You'd have to know some relationship, formula, equation etc. among the angles
and the lengths. There would be many relationships to choose from if the items
you mention are the parts of a triangle, but if they are, you've kept it a secret.

How do you find a missing angle in a quadrilateral with variables involved?
The method will depend on what information you have, and the amount of knowledge expected of you. At the basic level, you should be able to reach an answer using the following facts: 1. The sum of the exterior angles is 360 degrees. 2. The sum of the interior angles is 360 degrees. 3. Each pair of exterior and interior angles adds to 180 degrees. These will give equations that may be solved - individually or simultaneously (depending on your level). If you are more advanced still, information about some of the angles may be missing but you may have side-lengths instead. Then it is a question of using the basic triginometric ratios to calculate the missing angles.
What is the measure of the angle named x?
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
If two angles in a triangle are 20 degrees and 90 degrees what is the measure of the missing angle?
70 degrees
How do you calculate angle in a trapezium?
You need to use a protractor to measure the two angles at the ends of the base. The other two angles will be their supplements.
A rhombus has angles measuring 143 degrees 143 degrees and 37 degrees the measure of the missing angle is?
It is 37.
How do you calculate the missing degree of a triangle?
The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.ExampleTwo angles of a triangle are 35o and 62o. What is the third angle?Solution180o - (35o + 62o) =180o - 97o = 83o
What is the formula for finding a missing angle of a triangle when there are no other angles available?
If you have the lengths of all three sides than ÐA = cos-1[(b2 + c2 - a2)/2bc] where a, b and c are the lengths of the sides and A is the angle opposite side a.
25 39 what is the missing angle?
If they are the angles of a triangle then the missing angle is 116 degrees
How do you determine the measurement of a missing angle in a angle?
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
How do you find a missing angle for a triangle?
Subtract the two known angles from 180 degrees will give you the missing angle
How do you find the perimeter of a triangle if only 2 side are given for grade6?
You can't. To calculate another side length you need an angle. you need either two angles and a side length, or two side lengths and an angle to solve for other angles or side lengths. No matter what the case, you need three pieces of information i do not understnd it
How do you find the missing angle of a triangle if you are given two of the angles?
180 minus two known angles = unknown angle
How do you calculate the missing length of a triangle?
It depends on what other information you have. Knowing the lengths of two sides of a triangle is not enough to calculate the third. You need to have some further information: and angle, the area, the length of an altitude or a median.
What is a supplementary angle and what does it measure?
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
How do you classify by it measure of its angles and the lengths of its side?
Angle Classifications:Obtuse (1 angle >90 degrees)Acute (all 3 angles
Is there angle with same length and angle?
Angles do not have lengths so there is only one characteristic - not two that can (or cannot) be the same.
How do you find the missing angle of a square with no given angles?
All the angles of a square are 90 degrees.
