A) Angle A has to be congruent to Angle D
Area is 92.13 and the perimeter is 47.42 i think it’s correct
<span>First of all in order to find the exact value by using a half angle identity we will do
cos(5π divided by 12)
=cos (5π divided by 6) divided by 2
= ± Under root[(1+cos (5π divided by 6) divided by 2]
Now we will consider + sign because 5π divided by 12 is in quadrant. where cos>0
so the solution is [(1- Under root 3 divided by 2) divided by 2]
We will ignore the negative sign
I hope it helped.</span>
Y-int, x=0
y = 2(0) therefore y-int is (0,0)
x-int, y=0
0=2x
x = 0 therefore x-int is (0,0)
The answer is 2.24
Hope this helps
