Answer:

x = 20

Step-by-step explanation:

angles are adjacent and add up to 180 degrees, so:

7x + x + 20 = 180

8x + 20 = 180

8x = 160

x = 20

A suitcase measures 24 inches long and 18 inches high, what is the diagonal length of the suitcase?

pickupchik [31]

Answer:

The diagonal is 30 inches

Step-by-step explanation:

Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this

a² + b² = c²

so we plug our two values to find the diagonal (hypotenuse)

24² + 18² = c²

576 + 324 = c²

900 = c²

c = √900

c = 30

The diagonal is 30 inches
