opposite/hypotenuse = sin(x)
adjacent/hypotenuse = cos(x)
opposite/adjacent = tan(x)
where 'x' is the angle in question.

What is a right scalent triangle?
A right scalent triangle is a triangle with a right angle and no sides equal in length.
In a right triangle the ratio of the length of the side opposite an acute angle to the length of the hypotenuse?
sin θ : 1 = the length of opposite side to angle θ : the length of the hypotenuse
If you divide length of the opposite side of an angle in a right triangle by the length of the adjacent side what value do you get?
It is a tangent.
A triangle has an angle of 15 degrees. The side opposite the angle is 1.2m in length. How would you find the base of the triangle Not the hypotenuse?
Assuming this is a right triangle. the tan of an angle is the side opposite over the side adjacent. We know the side opposite, we need to find the side adjacent, we will assign this unknown side temporarily as x. tan(15) = 1.2 / x x = 1.2 / tan(15) x (the side adjacent) is approx. 4.49 m
If one angle of a triangle measure 32 and another angle measures 71 what is the measure of the third angle?
77. The sum of the three angles in a triangle equal the sum of 180 degrees
Is a triangle with the length of 72425 a right angle triangle?
No way to tell as we don't know an angle or another side.
What triangle has one right angle and two sides the same length?
An isoceles triangle has two angles that are the same length with the third being different. It can be a right angle or another angle. or it's also called a Right Isosceles triangle.
How do you find an unknown angle of a triangle without having a length of one of the sides using sohcahtoa?
If you have the length of two of the sides and one other angle you can use the law of sines.
Is it true the sine ratio relates the length of the leg the angle that is in question to the length of the hypotenuse?
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
What is theta?
It is a greek letter which is used to mark an unknown angle in a triangle when you are going to use trigonometry to work it out, eg. sin(theta)=length of opposite side/ length of hypoteneuse
How do you use sine in math?
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
What is the formula to find the length of a right angle triangle?
By using Pythagoras' theorem for a right angle triangle.
A triangle has one angle of 80 degrees and another of 60 degrees how many degrees must there be in third angle?
The internal angles of a triangle add up to 180 degrees. 80 + 60 = 140 140 + x = 180 (x= the unknown angle) x = 180-140 x = 40 The unknown angle is 40 degrees
How long must a right triangle be?
It can be any length; a right angle triangle just needs to include a right angle somewhere. But length has nothing to do with whether it is a right angle or not.
What is right angle triangle and isoceles triangle?
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
What ratio relates the length of the leg opposite the angle in question to the length of the leg adjacent to the angle?
This ratio is the tangent of the angle.If the triangle is a right angled triangle and the angle in question is not the right angle, then it is the tangent of the angle in question.
What does right isosceles mean?
An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
