Answer:
Option A 90,68


Step-by-step explanation:
see the attached figure to better understand the problem
The figure shows a kite
we know that
A kite properties include
1) two pairs of consecutive, congruent sides
2) congruent non-vertex angles
3) perpendicular diagonals
Find the measure of angle 1
we have that
----> by the diagonals are perpendicular
Find the measure of angle 2
we know that
triangle AEB is congruent with triangle CEB
so

In the right triangle EAB
----> by complementary angles in a right triangle
so

therefore

Answer:
2√14
Step-by-step explanation:
√56
√2^2 x 14
√2^2 √14
2√14
Answer:
circumference is 81.68
area is 530.93
Step-by-step explanation:
C=2πr=2·π·13≈81.68141
A=πr2=π·132≈530.92916
Y=6x^2 -5x+6 ( the first option )
Hey there,
So when finding the perimeter, we do addition.
So . . .
20 + 12 + 18 + 7+ 13+6
Your correct answer would be 76
Hope this helps.
