A) Angle x = 180 - (50+60) = 70

B) Angle x = 180 - (90+30) = 60

C) Angle x = 180 - (110+30) = 40

D) 50+2a = 180

or, 2a = 180-50

or, a = 130/2 =65

E) 3a = 180

or, a = 180/3 = 60

F) 3a+90 = 180

or, 3a = 90

or, a = 90/3 = 30

Answer:

A: 70 degrees B: 60 degrees C: 40 degrees D: 65 degrees and 65 degrees E: 60 degrees F: a= 30 degrees

Explanation:

To find the missing angle you will have to use the angles that are provided for you so if there is a square in any of the corners that automatically equals 90 degrees, once you add that with the other number degrees just subtract their sum from 180 degrees. BUT if that is not the case and i only gives you on angle that you will just need to use critical thinking to see what is left in the equation and see how it plays out with the angle given and the other angle that you need to find to see if it gives you 180 degrees.
