Answer:
108° or Red
Step-by-step explanation:
This looks closest to a 108° angle.
108 - 7 = 101
101 ÷ 5 = 23
x = 23
Do the simple math for the rest of the angles...
Here is the math from where that leaves you...
127° (b) + 90° (d) + 136° (e) + 79° (a) + 108° (c) = 540°
P.S.
Rectangle answer must be 360° because 90° × 4 = 360°
Any additional vertices equals another 180° to the final number.
