What is the formula of a acute angle?
The formula for calculating the measure of an acute angle is not specific, as the measurement of an angle is determined by the degree of rotation between two lines. However, in a right triangle, the acute angles can be calculated using the trigonometric functions such as sine, cosine, and tangent.
Is sine considered as trigonometry?
Yes, the sine, cosine and tangent are integral to problem solving (angles and side lengths) in right angle triangles (triangles with a 90 degree angle included).
How do you find sides of right triangle given only the hypotenuse and all angles?
One is the hypotenuse times the sine of one acute angle, the other, the hypotenuse times the sine of the other acute angle (or the cosine of the first).
What is sine in trigonometry?
The sine of one of the acute angles in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
How do you find the length of a leg and a hypotenuse when you only have one measure of one leg?
It's impossible. Trigonometrical functions can be used, but only if the measure of one of the acute angles is given. If it is given, then knowing that the right angle is 90 degrees you can solve for the other acute angle. Then use sine, cosine, or tangent to relate the measure of the sides, for which a calculator is necessary.
