Question

Use the diagram at the right to answer questions 7-11.

Answer 1

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:

First Rule : Sum of angles of the triangle is 180°.

um of angles of the triangle is 180°

Second Rule : Sum of supplementary angles (angles of straight angle) is 180°.

Third Rule : 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)

Hope this helps.. Good Luck!
