How do you determine sine in a right triangle?

The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.


Are the hypotenuse of a right triangle adjacent to the right angle?

First: there can only be one hypotenuse in a right angled triangle and it is always OPPOSITE the right angle, NEVER adjacent.


How do you find the width and length of a rectangle knowing ONLY the diagonal and its angle?

By using the trigonometric ratios of Sine and Cosine. The diagonal forms the hypotenuse of a right angled triangle with the length and width of the rectangle forming the other two sides of the triangle - the adjacent and opposite sides to the angle. Then: sine = opposite/hypotenuse → opposite = hypotenuse x sine(angle) cosine = adjacent/hypotenuse → adjacent = hypotenuse x cosine(angle)


What is the opposite of a acute angle?

No such thing as opposite of acute angle. An ACUTE angle is an angle of less than 90 degrees. A RIGHT angle is an angle of 90 degrees only. An OBTUSE angle is an angle between 90 degrees and 180 dehrees. An angle of 180 degrees is a straight line. A REFLEX angle is an angle between 180 degrees and 360 degrees.


Can you find the hypotenuse of a right triangle when only one side length is known and all three angles?

Yes. You will need to use trigonometry. sin (angle) = opposite/hypotenuse cos (angle) = adjacent/hypotenuse tan (angle) = opposite/adjacent

The side of a triangle is always opposite the angle with the largest measure?

No, this statement is not correct. The side opposite the largest angle is the longest side of a triangle only if the triangle is obtuse. In acute triangles, the side opposite the largest angle is the longest side, and in right triangles, the side opposite the right angle (90 degrees) is the longest side.

How do you find the angle opposite of the hypotenuse of a triangle with all three sides known?

The only triangle that has a hypotenuse is a right-triangle. The hypotenuse is the side opposite the right angle, so the angle is always 90 degrees. In this case, if you're just finding the angle then you don't need to know what the side lengths are.


Find hypotenuse only using opposite and angle?

In a right angles triangle the sides are named the hypotenuse (the side opposite the right angle) and the other two sides are called the adjacent and the opposite sides. 1) The sine of an angle = length of the opposite side ÷ length of the hypotenuse. 2) The cosine of an angle = length of the adjacent side ÷ length of the hypotenuse. Using 1) The length of the hypotenuse = length of the opposite side ÷ the sine of the angle. Using tables or a calculator obtain the sine of the angle and divide this into the length of the opposite side. The result will be the length of the hypotenuse.

What is equivalence logic?

1. A triangle is a right triangle if and only if it has a right angle. 2. A triangle has a right angle if and only if it is a right triangle.


A Angle formed by opposite ray is?

An angle cannot be formed by only one ray. However, an angle formed by two opposite rays is called a straight angle.


What two dimensional figure has opposite side parallel and four right angles but not four equal sides?

The shape can only be a rectangle! A rectangle is a four-sided 2-dimentional figure, where every angle is a right angle, opposite sides are parallel, but the 4 sides are NOT equal.


How many angles does a right angle have?

A right angle only has one angle.
