Option D
Step-by-step explanation:
<u><em>The measure of the exterior angle is equal to the sum og non-adjacent interior angle</em></u>
=> 105 = 55 + x
<em>Subtracting 55 to both sides </em>
=> x = 105-55
=> x = 50 degrees
Answer:
D. 50°
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
180 - 105 = 75
Angles in a triangle add up to 180 degrees.
180 - 55 - 75 = x
50 = x

Let x = number of students in each of the remaining rows
266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
