An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, altitude divides the base into two equal segments. The altitude length is 30 inches and the base length is 15 inches. Find the perimeter of the triangle. Round to the nearest tenth of an inch.

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
