Answer:

108°

Step-by-step explanation:

Sum of interior angle of any polygon = (n - 2 )*180

Here, n = number of sides

Sum of interior angle of regular pentagon = ( 5 - 2)*180 = 3*180 = 540°

In regular pentagon all the angles are congruent.

Interior angle of regular pentagon = 540/5

= 108°

For A B and C, you just plug in the given number

A
$2(15) + 5 = 35$
B
$4(20) + 2 = 82$
C
$6(10) + 5 = 65$
And for D, you set the equation to 26 and solve for n
$3x + 5 = 26 \\ 3x = 21 \\ x = 7$
I had to use x instead of n, but for D n=7. :)
