You need to carpet a new office room. the new room is 12 feet by 15 feet 6 inches. a supplier delivered 20 square yards of carpe

vesna_86 [32]

First, determine the area of the floor of the new room by multiplying the dimensions in feet.
Area = (12 ft)(15.5 ft) = 186 ft²
Then, we convert the calculated area to yards
(186 ft²)(1 yd/ 3 ft)² = 20.67 yd²
Given that the supplier only delivered 20 yd², approximately 0.67 yd² of your floor will not have carpet.

Since the triangle is equilateral, all its angles are equal to 60°

AO is the bisector⇒∠OAD = 30°

AO is the hypotenuse, ∠OAD = 30°⇒

OD=5*2=10m

By the Pythagorean theorem

$10^2=AD^2+5^2\\AD=\sqrt{100-25} \\AD=\sqrt{75}$
