To find the altitude of a triangle, we can use the formula: area = 0.5 * base * altitude. Given that the area is 45 cm² and the base is 15 cm, we can plug these values into the formula: 45 = 0.5 * 15 * altitude. Solving for altitude, we get altitude = 45 / (0.5 * 15) = 45 / 7.5 = 6 cm. Therefore, the altitude of the triangle is 6 cm.

An isosceles triangle has two equal sides that are 15cm long and two equal angles of 62 degrees calculate the length of the third side?
first find the unknown angle, 180o - (62o+62o) = 56o next use the law of sines to find the other side: sin 62o / 15cm = sin 56o / X Solving for x, X = 14.08 cm
