3^2 + height^2 = 9^2
9 + height^2 = 81
height ^2 = 72
height = sqrt(72)
<span>f (n + 1) = f(n) + 2 so c is the answer

“S” = 3g /2n

Given:
A figure of a quadrilateral.
To find:
The measures of angle 1 and angle 2.
Solution:
The given figure has two pairs of congruent adjacent sides. So, the quadrilateral in the figure is a kite.
We know that the diagonals of a kit are perpendicular to each other at the point of intersection.

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.




Therefore, the correct option is C.
2/3 + n = 2n + 3 <== ur equation
2/3 - 3 = 2n - n
2/3 - 9/3 = n
-7/3 = n <== ur solution
or
2/3 + n = 2n + 3...multiply everything by common denominator of 3
2 + 3n = 6n + 9
2 - 9 = 6n - 3n
-7 = 3n
-7/3 = n
