Answer 2

hi friend

here's your answer looking for

if A= 4x-5

and,

C= 3x+10

so,

angle A= angle C. ( opposite angles of parallelogram )

so,

\begin{gathered}(4x - 5) = (3x + 10) \\ \\ 4x - 3x = 10 + 5 \\ \\ x = 15\end{gathered}(4x−5)=(3x+10)4x−3x=10+5x=15 

now,

Angle A = 4x-5

=4(15)-5

=60-5

=55

and,

angle A + angle B = 180

55+ angle B = 180

angle B = 125

hope you are satisfied with my answer
