Right Angle:A right angle is an angle of exactly 90 degrees, such as the corners of a square. It is also a part of a right triangle, which is necessary for some basic trigonometry formulas to work(such as sohcahtoa).Answer and Explanation: ...
If you have a right triangle where the hypotenuse is 17m, the adjacent side is 15m, and the opposite side is 8m, what is the measure of the angle between the opposite side and hypotenuse? What is the length of the side opposite to a 30 degree angle if it is 12 units less than th...
Answer to: In triangle ABC, angle B is a right angle and the measure of angle A is 40 degrees. Given that AC = 15, what is AB to the nearest tenth?...
The altitude of equilateral triangle ABC is 15. What is the length of a side of triangle ABC?Altitude of an Equilateral Triangle:Consider an equilateral triangle of side {eq}x {/eq} and altitude x. Then we get: Applying Pythagoras theorem to this triangle: ...
Since the length of a leg can never be greater than the length of the hypotenuse, it implies that the sine ratio can never be greater than 1. Answer and Explanation: Note from the given diagram that the measure of angle B is {eq}60^\circ. {/eq} The length...
