I hope it's help u!!!

Answer 2

Answer:

by connecting l and m and forming a triangle

the 2 angles corresponding to 35 and 40°

will be 90-35 and 90-40

=55 and 50°

(since l//m and connecting line is perpendicular)

therefore the third angle in the triangle will be

55+50+3rd angle =180

3rd angle =75°

now 3rd angle + X=360

75+X=360

X=285°(ANS)
