Question

determine the angles of each the following figures
(x+10)
130°​

Answer 1

Sum of interior angle of quadrilateral = 360°

50° + 130° + 120° + x = 360°

300 + x = 360

x = 360 - 300

x = 60

x = 60°

Answer 2

Answer:

x=40 and x+10 =50

Step-by-step explanation:

the sum of all angles is 360

130+130+(x+10)+(x+10)=360

260+x+10+x+10=360

280+2x=360

2x=360-280

2x=80

x=80/2

x=40
