The number you've got in Step 2 is the longer leg. 2. For right triangles only, enter any two values to find the third. Approved. Q: Use the Law of Cosines to find the values of x and y. X (Round to two decimal places as needed.). ___cm Thank you Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website! A: we know the sum of angle of trianle is 180. The other two sides of the triangle, AC and CB are referred to as the 'legs'. Angle C = 90 degrees, angle A = 40 degrees, and angle B = 50 degrees. Then, another side is x+4.The length of the opposite side=4+6=10. 16/9 = Weegy: Whenever an individual stops drinking, the BAL will decrease slowly. Let P be the mid-point of the hypotenuse. Find the area of a rhombus if its vertices are (3, 0), (4, 5), ( 1, 4) and ( 2, 1) taken in order. Michelle spent $32 on hot dogs and hamburgers. 20. WebIf the altitude is drawn to the hypotenuse of a right triangle, then the two triangles formed are similar to the original rectangle and to each other. If your triangle has sides of 3 and 4, and you have assigned letters to those sides such that a = 3 and b = 4, then you should write your equation out as: When you plug those values into your equation, it should now look like this: The ratio of a Pythagorean triple holds true even when the sides are multiplied by another number.
