Question

FIND X ONLY , FOR GRADE 7 PLS

Answer 1

Answer:

E+ F+ D= 180° ( angle sum property of triangle)

42° + 28° + D = 180°

D = 180° - 70°

= 110°

Now,

110° + x = 180°(straight line)

x= 180° - 110°

=70°

Answer 2

Answer:

by using angle sum property in triangle DEF -

42°+ 28° + angle EDF = 180°

angle EDF = 180 - 70° = 110°

: angle EDF = 110°

Now, x + EDF = 180°

x + 110° = 180°

x = 70°

HENCE, SOLVED.
