Two observers on the ground 1.5 mi apart see a helicopter in the air directly between them. The angles of elevation from the observers to the helicopter are 30° and 35°.
Find the altitude of the helicopter.

That table shows measurements (in invhes$ from cubes with different side lengths. which pairs of variables have a linear relationship? check all that apply

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1
