Astudent scored 83 and 91 on her first two quizzes write and solve a compound inequality to find the possible values for a third quiz score that would give her an average between 85 and 90, inclusive

70.30

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
