By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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


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 the length of a right angle triangle with a height of 7 cm and the hypotenuse is 13 cm?

10.95 cm


Fill in the blank If the shortest leg of a 30-60-90 triangle has length 11 the length of the hypotenuse is?

22, The shortest side is opposite the smallest angle. As it is a right angle triangle, the Sine ratio can be used: Sine = opposite/hypotenuse ⇒ hypotenuse = opposite/sine = 11/sine 30o = 11 ÷ 1/2 = 22


The hypotenuse of isosceles right triangle measures 15 feet. what is the area?

I believe you need 2 pieces of data (either an angle or another length) before you can calculate anything about the triangle. Anyone else can correct me if I'm wrong.

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.


How do you calculate the hypoteneuse?

If it's a right angle triangle then:- a2+b2 = c2 where 'c' is the hypotenuse and the square root of this is the length of the hypotenuse when 'a' and 'b' are the other sides of the right angle triangle.


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.


How do you calculate the length of the opposite and adjacent sides in a right angle triangle if you know the length of the hypotenuse and the angle between the adjacent and hypotenuse?

the sides can be found out by using trignometry.. sines and cosines.. sine of an agle is perpendicular/hypotenuse cosine of an angle is base/hypotenuse..


In a right triangle the sine of any angle is?

The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.


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


What is the hypotenuse if the legs are 39 and 80?

The hypotenuse of the right angle triangle is 89 units in length


If you divide length of the opposite side of an angle in a right triangle by the length of the hypotenuse what value do you get?

You get the sine of the angle. For a right triangle: sin (x) = opposite/hypotenuse cos (x) = adj./hypotenuse tan (x) = opposite/adj


What is the length of the hypotenuse of a right triangle whose legs measure 30 in and 72 in?

Using Pythagoras' theorem for a right angle triangle its hypotenuse length is 78 in.


What is the ratios function of sin?

The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.


How do you calculate sine?

The sine of an angle of a right triangle - which is a triangle containing one 90o angle - is calculated as the length of the side opposite the angle divided by the length of the hypotenuse. For very small values of x, sin(x) is approximately equal to x.


What is the length of the hypotenuse if a triangle has legs 25 cm and 37 cm?

If it's a right angle triangle then using Pythagoras' theorem then the length of the hypotenuse is about 44.65422712 cm
