Answer:
47°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles
124° is an exterior angle , thus
77 + ? = 124 ( subtract 77 from both sides )
? = 47°
Factoring the common factor (n-3) from the terms on the left side, that left-side expression becomes
(2n^2-4)(n-3)
We presume your missing factor is
(2n^2-4)
Answer:
20
Step-by-step explanation:
ii) 7, 12, 17, 22..
The difference between the i) pair is 3, and the ii) pair is 5.
So ,
17 + 3 = 20.
22 + 5 = 27.
Therefore the series is 8, 7, 11, 12, 14, 17, 17, 22, 20, 27.
Answer:
The perimeter of a circle is π × d. Here's is the diameter of the circle. Hence, the perimeter of a circle is half of that of the circle that is ½ π × d.
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
