If the lengths of the sides of the right angle have lengths 1" and 5", then by the Pythagorean Theorem, the hypotenuse has length √26". The hypotenuse is always the longest side of a right triangle. If θ is the angle opposite the side of length 5", then tanθ = opposite / adj...
A right triangle has side lengths 9, 40, and 41 as shown below. Use these lengths to findtanM,cosM,andsinM. Trigonometric Ratios: Trigonometric ratios are those that link the sides of a right triangle depending on their angles. A right ...

17.The right-angled triangle ABC has sides with lengths aand b as shown. The ratio of the area of the shadedsquare to the area of triangle ABC is a (ab)/(a+b) (ab)/((b-a)^2) (2ab)/(a^2+b^2) (2ab)/((a+b)^2) (ab)/((a+b)^2) _2(E 相关知识点: 试题来源:...
To find the length of the hypotenuse in right triangle ABC with legs a = 6 cm and b = 4.5 cm, we can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the sq
Now, let's check how finding the angles of a right triangle works: Refresh the calculator. Pick the option you need. Assume that we have two sides, and we want to find all angles. The default option is the right one. Enter the side lengths. Our right triangle has a hypotenuse equal ...
A right triangle is triangle with an angle of ( radians). The sides , , and of such a triangle satisfy the Pythagorean theorem (1) where the largest side is conventionally denoted and is called the hypotenuse. The other two sides of lengths and are called legs, or sometimes catheti....
