5.2 7 + 3⅔
5.3⅔×⅚
5.4 0,9 x 0,3
5.5 84 - 0,7

Based on the diagram, match the trigonometric ratios with the corresponding ratios of the sides of the triangle. tiles : cosb sinb tanb sincposs matches: c/b b/a b/c c/a

The legs of a right triangle measure 6 meters and 8 meters. what is the length of the hypotonuse.

If 7x=9y, y/z = 7/5 , then x/z = (a) 2/7 (b) 7/9 (c) 9/5 (d) 9/7 (e) 5/9
