What is the answer? X=

x=30°

Step-by-step explanation:

every triangle has 180°

look at these following statements:

Corollary 1: An equilateral triangle is also equiangular.

Corollary 2: An equilateral triangle has three 60 degree angles.

Corollary 3: The bisector of the vertex angle of an isosceles triangle is perpendicular to the base at its midpoint.

these prove that this is an equilateral triangle, so the top angle should also be 60° BUT it is split in half by a angle bisector, which means x=30

Hope this helps:)

the answer is true.

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
