The principal of a school asked all 7th grade students, "Would you prefer to add pizza or hamburgers to the had to choose one of the two choices. The survey showed that 38% prefer to add hamburgers.

Choose all of the statements that are valid conclusions based on the data.

A. all of the students at the school prefer pizza to hamburgers

B. 62% of the 7th grade students at the school prefer to add pizza

C. 38% of all of the students at the school prefer to add hamburgers

D. all of the 7th grade students at the school like pizza and hamburgers

E. 38% of the 7th grade students at the school prefer to add hamburgers

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.

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
