Step-by-step explanation:
∠2 and ∠3 are same- side interior angles and are supplementary.
Answer:
Minimum 66 feet of molding that he needs.
Step-by-step explanation:
Given that a square ceiling has a diagonal of 23 ft.
If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²
⇒ 2a² = 23²
⇒ a = 16.2634 feet (Approximate)
Now, the perimeter of the square ceiling will be 4a = 65.05 feet.
If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)
Circle b:
Diameter = x
Radius =
Area =
Circle a:
Diameter =
Radius =
Area =
Thus,
Area of circle b to area of circle a
=
÷
=
×
= 4
Hence, the area of circle b is
4 times the area of circle a.

The answer is b (1,-1)
Answer:
9/22
Step-by-step explanation:
1/2 + x=10/11
Subtract 1/2 from each side
1/2-1/2 + x=10/11-1/2
x = 10/11 -1/2
Getting a common denominator of 22
x = 10/11*2/2 -1/2 *11/11
x = 20/22 - 11/22
x = 9/22
