Answer:
7. a= 110°
8. b= 70°
9. e= 140°
10. h= 150°
11. i= 150°
Step-by-step explanation:
I put the following rules in case you forgot them:
<u>First Rule</u> : Sum of angles of the triangle is 180°.
um of angles of the triangle is 180°
<u>Second Rule</u> : Sum of supplementary angles (angles of straight angle) is 180°.
<u>Third </u><u>Rule</u> : Vertically Opposite Angles are equal.
7. Find the measure of a
a= 180° - 30° - 40° = 110° (using first rule i wrote it above)
8. Find the measure of b.
b= 180° - a = 180°- 110°= 70° (using second rule where a and b are supplementary angles)
9. Find the measure of e.
e= 180° - 40°= 140° (second rule where angles 40° and e are supplementary)
10. Find the measure of h.
h= 180° - 30°= 150° (second rule where h and the angle 30° are supplementary angles)
11. Find the measure of i.
i = h = 150° (third rule where i and h are vertically opposite angles)
