A, the relationship lasts over a given period of time.
Answer:
A. 149
Step-by-step explanation:
When a quadrilateral is inscribed in a circle, the sum of the opposite angles in the quadrilateral equal (180) degrees. Applying this theorem here, one can state the following:
c + 31 = 180
Inverse operations,
c + 31 = 180
c = 149
Thus, option (A) is the correct angles: ( c = 149°)
#1 = 12 units
#2 = 5.1 I think

Correct question : the width of a rectangle is half of the length. The area is 25 square meters. What is the perimeter ?

Let the Length of the rectangle be 2x m and width be half of the length that is ( 2x ÷ 2 ) = x m
We know, Area of Rectangle = length × width
Applying formula,
=> 25 = 2x × x
=> 25 = 2x²

=> 12.5 = x²
=> ±√12.5 = x
Dimensions can't be negative, taking positive value,
Therefore,
Breadth = x = √12.5 m
Length = 2x = 2√12.5 m
We know, perimeter of Rectangle = 2( Length + Breadth)
Then,
Perimeter = 2( 2√12.5 + √12.5 ) m
Perimeter = 2( 3√12.5 ) m
Perimeter = 6√12.5 m
Hence, perimeter of the rectangle is 6√12.5 m
It is four and three fourths inches. (4 3/4 inches)
