3. Bellwork A male punky fish has 9 stripes, while a female punky fish has 8 stripes. If the number of stripes on all the punky fish in a tank totals 86, what is the ratio of male fish to female fish? A male punky fish has 9 stripes, while a female punky fish has 8 stripes. If the number of stripes on all the punky fish in a tank totals 86, what is the ratio of male fish to female fish? Two triangles of equal area have congruent sides as shown. Determine the degree measure of x, the smaller of the two vertex angles. Two triangles of equal area have congruent sides as shown.
