A.16
B. 8
C. 4
D. 12

Answer 1

what kind of triangle is that

Answer 2

idk

Answer 3

Isosceles and Equilateral Triangles

Answer 4

it's an isosceles triangle since those two angles are equal. knowing that it's an isosceles triangle, MN should be equal to ML. so x + 8 = 3x. solve for x and then plug that back into x + 8

Answer 5

i did x+8 = 3x and i did 3x-1x=2x and i did 8/2 = 4 is that right

Answer 6

yea, x should equal 4

so x + 8 = 4 + 8 = ?

Answer 7

so its 12

Answer 8

yes :]
