HELP ME , Im Failing Math :/ 3. Which set of lengths could be the side lengths of a right triangle? (1 point) 20 cm, 22 cm, 29 cm 10 ft, 12 ft, 15 ft 7 km, 24 km, 28 km 13 in, 84 in, 85 in 4. A right triangle has a side length that measures 4 m and a hypotenuse that measures 8.5 m. What is the measure of the other side of the triangle? (1 point) 7.5 m 8.1 m 9.4 m 9.8 m 5. You want to divide a square piece of paper into two equivalent triangles. If the square measures 20 cm on each side, what will the third side of each triangle measure? (1 point) 8.9 cm 20 cm 28.3 cm

    Right angled triangle follows a law, the pythagorean law.\[(hypotenuse)^{2}=(perpendicular)^{2}+(base)^{2}\] \[a ^{2}=b ^{2}+c ^{2}\]

    \[a) 29^{2}=22^{2}+20^{2}\]841=844 (Don't satisfy) b)\[15^{2}=12^{2}+10^{2}\]225=244 (Don't satisfy) c)\[28^{2}=24^{2}+7^{?}\]784=625 (Don't satisfy)

    try last option by yourself. remember the longest side will always be the hypotenuse.
