What is cos 30?this is geometry
2 answers:
So the definition of the cosine of an angle of a right triangle is 
. You may remember this by SohCahToa (sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, tangent is opposite over adjacent).
Remember, adjacent refers to the side next to the angle in question, and the side can't also be the hypotenuse. The hypotenuse is that longest side and is opposite the right angle.
We have the cosine of 30°. We write

Answer:
The measures of angle are 46 degrees and 134 degrees.
Step-by-step explanation:
We are given the following in the question:
Let the measure of one the of the supplementary angles be x degrees.
Measure of other angle =
Since, the two angles are supplementary, their sum is 180 degrees.
Thus, we can write and solve the equation:
Thus, the measures of angle are 46 degrees and 134 degrees.
