Question

8 what is the measure of angle 3 + angle 4 + angle 5? * (25 points) 0 90 180 360

Explanation:

Step1: Recall angle - sum property

The sum of angles around a point is 360 degrees. Angle 1 + Angle 2+ Angle 3 + Angle 4 + Angle 5+ Angle 6 = 360 degrees.

Step2: Identify right - angle

Angle 1 is a right - angle and its measure is 90 degrees, and Angle 6 is also a right - angle with a measure of 90 degrees. So Angle 1+ Angle 6 = 180 degrees.

Step3: Calculate the sum of Angle 3, 4 and 5

(Angle 1 + Angle 2+ Angle 3 + Angle 4 + Angle 5+ Angle 6)-(Angle 1 + Angle 6)= Angle 2+ Angle 3 + Angle 4 + Angle 5. Substituting the values, 360 - 180=180 degrees.

Answer:

180
