Using the angle addition theorem, the measure of angle 2 in the given diagram is: m∠2 = 35°
<h3>What is the Angle Addition Theorem?</h3>
Based on the angle addition theorem, the sum of two smaller angles that make up a bigger angle equals the sum of the bigger angle.
Given the following:
m∠EBC = m∠EBD + m∠2 [angle addition theorem]
Substitute
55 = 20 + m∠2
m∠2 = 55 - 20
m∠2 = 35°

Answer:
Mean: 17
Median: 16
Mode: 10
Step-by-step explanation:
8, 10, 10, 11, 16, 17, 19, 21, 41
Median: (the middle number in the number list/data set) 16
Mode: 10
Mean: 8 + 10 + 10 + 11 + 16 + 17 + 19 + 21 + 41 = 153/9 = 17
Let s represent the measure of the second angle. Then the sum of the three angles of the triangle is ...
... first + second + third = 180°
... 2s + s + (s+72°) = 180° . . . . substitute the given information
... 4s = 108° . . . . . . . . . . . collect terms, subtract 72°
... s = 27° . . . . . . . . . . . . . divide by 4
The first angle measures 54°.
The second angle measures 27°
The third angle measures 99°.
