WebIn a triangle ABC, if angle B is obtuse, what types of angles can angles A and C be? If five angles of a heptagon have measures of #80^circ, 85^circ, 175^circ, 90^circ, 140^circ#, and if the other two angles are congruent, what is the measure of each of the other two angles? Webwe know that Area = (base * height)/2 (formula for area of a triangle). if we know the area, suppose it is 4 for this example, and the height is 2 we get. 4= (x*2)/2. multiply by 2 on both sides to get. 8=x*2, divide both sides by 2 to get. 4=x, or 4=the base. use this method for the actual numbers.
