Answer 1

Answer:

REMEMBER, the total angle of a circle is 360°

A) x+120+60+70= 360

= x+ 250=360

=x= 360-250

X= 110°

‎ ‎

B) 100+80+90+x=360°

= 270°+x= 360

=x=360-270

X= 90°

‎ ‎

‎ ‎

E) 5x+5x+4x+3x+x=360°

= 18x=360°

= x= 360÷18

=x= 20°

Angles are = 100°,100°,80°,60°,20.

‎ ‎

‎ ‎

F) 6x+5x+x+5x+7x=360°

= 24x= 360°

=x=360÷24

=x=15

Angles are = 90°,75°,75°,15°, 105°

‎ ‎

‎ ‎

H) x+10= 40-x

(vertically opposite angles are always equal)

= x+x=40-10

=2x=30

=x=15°
