Pls help In the diagram below, DF = JL = a, FE=LK =b, and triangle DEP is a right triangle
Use the drop-down menus to complete the proof that if the equation of +62 = 2 is true of
the side lengths in triangle JKL, then triangle JKL must be a right triangle
D
F
E
Triangle DEF is a right triangle
of +67=²

49xy +34y - 72z. determine the degree of the polynomial

How do you use the elimination method for this question? explain, because i really want to understand!

Stefano accidentally dropped his sunglasses off the edge of a canyon as he was looking down. the height, h(t), in meters (as it relates to sea level), of the sunglasses after t seconds, is shown in the table. during its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber? 166 meters 176 meters 230 meters 240 meters its b.176 i took the test 166 is wrong and 176 is correct
