An envelope is 48 centimeters wide, and it measures 52 centimeters along the diagonal. How tall is the envelope?

20 cm.

Step-by-step explanation:

Pythagorean Theorem a^2 + b^2 = c^2 (c is the hypotenuse).

Plug it in.

48^2 + b^2 = 52^2

2,304 + b^2 = 2,704

Isolate the variable.

b^2 = 400

b = 20

false
