The quicker way is to realize that x and y are complementary angles (add up to 90°). Then, using the complementary angle relationship for sine and cosine, which is $\sin(x°)=\cos(90°−x°)$, you realize that $\cos(y°)=0.6$. However, you can also solve this problem by constructing a diagram using the given information.
Jun 23, 2011 · Sines of other angles Many angles can be computed exactly by many methods. Another practical formula is the sine of 3 times an angle: sin 3A = 3 sin A − 4 sin 3 A. sin 9°: For example, the sine of 9 degrees is the sine of (3×3°). So, with A = 3, we arrive at. And so on.

Flip the paper, keep the protractor on the vertex, and measure from the dotted line to the angle line. Now, add the acquired angle to 180°. For example, if you counted 20° from the dotted line, the reflex angle measures 180 + 20 which is 200°. This is how you can use a protractor to measure as well as draw angles, quickly and easily.
Question 244488: find the measure of two complementary angles if the difference in teh measure is 16? Answer by checkley77(12844) ( Show Source ): You can put this solution on YOUR website!
The degree measure of angle A of isosceles triangle ABC is 30 degrees. Sides ABD and AC are equal. Find the shortest side of triangle ABC. Solution: We must find the degree measure of the other two angles of triangle ABC. Since the measure of angle A = 30 degrees, then it follows that the other two angles must be equal and add up to 150 degrees.
The difference in the measure of two supplementary angles is 36. What is the measure of the two angles? Geometry Angles and Intersecting Lines Complementary and Supplementary Angles. 1 Answer mason m Jan 2, 2016 #72˚,108˚# Explanation: Say that. #mangle1=x# #mangle2=x-36# ...
Apr 30, 2019 · Measures (in degrees) of two complementary angles are two consecutive even integers. Find the angles. Solution: Let one angle be 2x and the other angle be 2x + 2. We know that the sum of the measures of the complementary angles is 90° According to question, 2x + 2x + 2 = 90° ⇒ 4x = 90° – 2 = 88°
