PLEASE PLEASE DUE TODAY I Need To Find X Calling 10th Graders Or Geometry Will Give Brainliest And Points Please class=

Sagot :

angles sum: 180(6-2) = 720

50 + 37 + 42 = 129

129 + 5x + 7x - 1 + 3x + 40 = 720

15x + 168 = 720

15x = 552

x = 36.8

check:

129 + 5(36.8) + (3(36.8) + 40) + (7(36.8) - 1) = 720

Correct answer??

180-50 = 130

180-37 = 143

180-42 = 138

Known internal angles:

130 + 143 + 138 = 411

15x + 39 + 411 = 720

15x = 270

x = 18
x = 36.8
I’m sure of it
