Find the value of w

Leave answer in surd form

w =

Step-by-step explanation:

Applying 3 applications of Pythagoras' identity on the 3 right triangles from left to right.

Left right triangle ( finding vertical side v ), then

v² + 7² = 9²

v² + 49 = 81 ( subtract 49 from both sides )

v² = 32 ( take the square root of both sides )

v = = 4

------------------------------------------------------------------------

Middle right triangle ( finding hypotenuse h ), then

h² = 5² + v² = 5² + (4 )² = 25 + 32 = 57 ( square root of both sides )

h =

-------------------------------------------------------------------------

Right side right triangle ( finding hypotenuse w ), then

w² = 4² + h² = 4² + ( )² = 16 + 57 = 73 ( square root of both sides )

w =

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
