Given:
A regular polygon with three vertices and side 14 cm.
To find:
Area of the regular polygon.
Solution:
We know that, a regular polygon has equal sides and equal interior angles.
The given regular polygon has three equal sides, it means it is an equilateral triangle.
The area of an equilateral triangle is:

Where, a is the side length of the triangle.
Putting
, we get




Therefore, the area of given regular polygon is 84.9 cm².
Answer:
Graph A
Step-by-step explanation:
Graph A since 11/8 is equivalent to 88/48
Hello! Charchar here!
Answer:
Ans: n = -4
Step-by-step explanation:
General equation of the Line that passes through the 2 points
A(1, 1) and B(-2, 4) --> y = ax + b.
A(1, 1) --> 1 = a + b (1) --> b = 1 - a
B(-2, 4) --> 4 = -2a + b (2).
4 = -2a + 1 - a --> -3a = 3 --> a = -1 --> b = 1 -(01) = 2
Equation of the line AB --> y
=
−
x
+
2
Write that the line AB passes through C (6, n):
n = - 6 + 2 = -4

Hope this helped!
Have a nice day!
