PLEASE HELP !! EMERGENCY

Answer 1

.11. What is the measure of a base angle of an isosceles triangle if its vertex angle measures 30°?
150°

75°

30°

15°

Answer 2

150 IS THE ANSWER ?

Answer 3

It is NOT 150º -- Let's see: 30º + 150º + 150º = ?? Seems a lot more than 180º.

Answer 4

but 150+30 =180

Answer 5

dont get what you are trying to say ??? @tkhunny

Answer 6

Sum of interior angles of a triangle is 180º

If the vertex of an isosceles triangle is 30º, this leaves 180º-30º = 150º for BOTH base angles.

Answer 7

so that is why its 150 ! ?

Answer 8

wait its half of 150

Answer 9

75
