Answer:

29.4 degrees

a = 53 cm = opposite side to the angle

b = 94 cm = adjacent side to the angle \alpha

tan = opp/adjacent = 53/94 = 0.5638

\alpha = inverse tangent of .5638 = tan⁻¹ (.5638) = 29.4₋⁰

I am redecorating my home. I am adding tile to the kitchen which is 18' long and 16' wide. I am also tiling the master bathroom.
Romashka-Z-Leto [24]

Answer:

The kitchen requires 288 sq. ft. of tile

The master bathroom requires 180 sq. ft. of tile

In total, we will spend $1170


Step-by-step explanation:

The area of the kitchen is length * width:

Area of Kitchen = 18*16=288 sq. ft.

The area of the master bathroom is length * width:

Area of Master Bathroom = 12*15=180 sq. ft.


  • <u>Question 1: "How many square feet of tile do I need for the kitchen?"</u>

The kitchen requires 288 sq. ft. of tile

  • <u>Question 2: " How many square feet of tile will I need for the bathroom?"</u>

The master bathroom requires 180 sq. ft. of tile

  • <u>Question 3: "If the tile costs $2.50 per sq ft, how much money will I spend on tile?"</u>

In total, <u><em>we require 288+180=468 sq. ft. of tiles</em></u>. If $2.50 is charged per square feet, in total we will spend:

468*2.5=1170 dollars
