Answer 1

What is the measure of the smallest angle?

Answer 2

52°
61°
67°
69°

Answer 3

do you know how many is the sum of measures of angles in a triangle ? so will get

2x +3x-11 +2x - 9 = S let being the sum of angles

7x -20 = S but you know that S=180

7x -20 =180

7x = 200

x = 200/7

angle A = 2x = 2* 200/7 = 400/7 = 57,1

angle B = 3x-11 = 3*200/7 - 11 = 600/7 -11 = 85,7 -11= 74,7

angle C = 2x -9 = 2*200/7 -9 = 48,14

so the smalest angle is C with 48,14 degree
