Thus, the hypotenusecis equal to the square root of the quantity legasquared plus legbsquared. Formula Two: Given One Leg and the Adjacent Angle Given the length of one leg and the adjacent angle, you can find the hypotenuse using the formula: ...
The hypotenuse leg theorem states that two right triangles are congruent if the lengths of the hypotenuse and any one of the legs of a triangle are equal to the hypotenuse and the leg of the other triangle. How to Find the Missing Hypotenuse? The missing hypotenuse can be easily known if ...
Pythagoras Theorem Hypotenuse NB c a b NB To find the Hypotenuse we must square the other sides and then add together. To find any other side we square the sides and subtract. The side is then found by taking the square root. Example Find the length of PQ correct to 2 significant figur...
If cos theta = {-8} / {17} and theta is obtuse, find, without using a calculator, the values of sin theta and cot theta. If tan (theta) = 0.5 and theta is not acute, what are the exact values of sin (theta) and...
Use a calculator and round your answer to the nearest tenth. Given a right triangle where the adjacent side b = 16 and hypotenuse c = 20. Find the opposite side a. How do you find leg length, BC, to the nearest tenth if, in a r...
Note that you could have chosen 33.5 degrees as instead of 56.5.You can find the sin and cosine values using a calculator. After simplifying everything the final answer would be c = 11.8 (rounded to the nearest 1st decimal place). Therefore the length of the hypotenuse of the right triangl...
