Question

please solve it...........​

Answer 1

180-55= 75

180-130=50

therefore, 75+50+90+x=360

215+x=360

360-215=x

x=45

Answer 2

first of all u shud label those angles in alphabets...

let the angle near 55° be A, the angle near 130° be B and the angle near x be C

and it is given that one of the side is 90°

to solve it by angle sum property

so,

55°+A=180°

A= 180-55

A= 125°

130°+B = 180°

B = 180-130

B= 50°

and one angle = 90°

by angle sum property:-

A+B+90°+C = 360°

125°+50°+90°+C=360°

265°+C= 360°

C=360-265

C = 95°

in order to find 'x':-

95+x=180°

x= 180-95

x= 85°

hope it helpzzz
