you will have two sides with measurements on them; your angle will be between to two. get me?
you would then type this in your calculator:
sin-1 (shift, then sin, ) , and don't press anything else, and then after that, type in
(one length), and then divided by (the other length) e.g :
sin-1 8 divided by 11.
you then write down the answer ( whole number because it is an angle), and there you go!
Just type in SOH/CAH/TOA in the Google search box and you will have a better description than i have given. if you have anymore questions on trigonometry then i will happily answer them. hope this helps as i have taken a long time to write it! Lauren.
If it's a right angle triangle then the the third angle is 60 degrees.
360 degrees
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
Subtract the two known angles from 180 degrees will give you the missing angle
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
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.
If it's a right angle triangle then the the third angle is 60 degrees.
There is no such thing as a regular trapezoid. REGULAR implies that all sides and all angles are equal. If that is the case, with a quadrilateral each angle would be 90 degrees, none would be 50.
360 degrees
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
The missing angle measure is 100 degrees.
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
Subtract the two known angles from 180 degrees will give you the missing angle
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
The TWO (not one) missing angles are 102 and 70
the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)
