What numbers are needed for: _*(_+_)/_=6

4(1+2)/2 = 6

Step-by-step explanation:

Think about multiples of 6 (I thought of 12)

"Think 'What' x 'what' will make the lowest multiple of 6"

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

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.
