Question

Triangle ABC is isosceles with AB=BC. If measure of angle A equals 30 degrees then find measure of angle B.

Answer 1

All triangle angles add to 180 degrees. You know that A = 30 and the other two angles are equal.
180 - 30 = 150 The remaining two angles total 150 degrees and they are equal.

Answer 2

Thank you so much!

Answer 3

so measure of angle B is 150?

Answer 4

No...two angles will equal 150...and the angles equal each other

Answer 5

ohhh so it would equal 75 degrees per angle?

Answer 6

yes!

Answer 7

75 + 75 + 30 = 180

Answer 8

okay! thanks a whole lot:)
