Question

Find the missing angle of the following quadrilaterals

Answer 1

ans 1
105° + 80° + 45° +2x-5 = 360°
225° + 2x = 360°
2x = 360 - 225
2x = 135
x =
$\frac{135}{2}$
ans 2
60° + 120° + 110° + x = 360°
290° + x = 360
x = 360 - 290
x = 70

pls mark me as brainliest

Answer 2

Q.2

60+110+120+x=360
290+x=360
x=360-290
x=70
