Question

please solve the question number 7 (2) number​

Answer 1

Answer:

25

Step-by-step explanation:

x+2x+x+20=120

4x=100

×=25....

Answer 2

Step-by-step explanation:

here , in figure let angle at the side of 120 be x .

so by angles in a linear pair.

120 +x=180

x=180 - 120

x=60

now the sum of all angles of a quadrilateral is 360 .

so,x+2x+(x+20)+60=360

4x+80=360

4x=360-80

4x=280

x=280÷4

x=70

now one angle is 2x that is 2×70=140

another angle is x+20=70+20=90

hope it helps !!
