Question

can someone tell me the answers please

​

Answer 1

Answer:

Some of 4 angles of quadrilateral = 360 degrees

here 3 angles are given and fourth we have to find

so, 60+130+120+ x = 360

i.e 310 + x = 360

i.e x = 360 - 310

x = 50

Fourth angle = 50 degrees

Answer 2

Answer:

60+130+x=180

190+x=180

x= 190/180

=90/85

=14/7

=2/1

=2
