A square brick is 11 inches on each side. What is the area of one face of the break?

Answers

All sides of a square are the same so if the length of one is is 11 inches, then all of the sides are 11 inches.
To work out the area of a square you multiply the length and the width.
In this case the sum would be: 11 x 11
The answer to that is 121.
So overall, the answer would be 121 inches.

PZ HURRY. find angle b.

Answers

Answer:

b = 60°

Step-by-step explanation:

If you look at the side under the 30° angle, there's a small red box, signifying a right (90°) angle. Doing the math, then, you would do:

90 = 30 + b

b = 60

60° if im not mistaken. the right angle is 90° and 30°+b is also 90° as 180°-90°=90°. therefore 90°-30°=60°. hope it helped!
