PQR is an equilateral triangle. PR and PQ are divided into 8 equal segments and corresponding points on those sides are joined to create 8 strips as shown. The line 24 is the bisector of angle PQR. QA cuts the shaded strip into 2 pieces. What is the ratio of the areas of those 2 pieces?

Convert the cartesian equation (x 2 + y 2)2 = 4(x 2 - y 2) to a polar equation. choices: r4 = -4r2 r2 = 4cos2θ r2 = 4sin2θ

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

The base of a triangle exceeds the height by 7 centimeters. if the area is 400 square centimeters, find the length of the base and the height of the triangle.
