SpletThe sum of the measures of all the angles in a triangle is always equal to 180o. In a right triangle, however, one of the angles is already known: the right angle, or the 90o angle. Let the other two angles be x and y (which will be acute). Applying these conditions, we can say that, x + y + 90o = 180o x + y = 180o − 90o x + y = 90o SpletFind the number of sides for a regular polygon whose measure of each interior angle is: a 108 b 144 arrow_forward The sides of a right triangle have lengths of 6cm, 8cm and 10cm. red cross help for refugees
