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.
3/20
step-by-step explanation:
well, there are 20 outcomes, and 3 of them you want. so, 3/20
h * s * a
h = history teacher
s = science teacher
a = art teacher.
i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
