Answer:If the vertex angle is x, then the base angle is 2x. Since the base angles of an isosceles triangle are equal, the other base angle is 2x.
The sum of the angles of a triangle are 180 so: x + 2x + 2x = 180 and x = 36 and 2x = 72.
Thus, the vertex angle is 36 degrees and the two base angles are 72 degrees each.
Step-by-step explanation:
Answer:
x^2 -2x = 4x+1
2x^2 +12x = 0
9x^2 +6x -3=0
Step-by-step explanation:
A quadratic equation has the highest power of x being squared
x^2 -2x = 4x+1
2x^2 +12x = 0
9x^2 +6x -3=0
These are all quadratic equations

HL Congruence Theorem
This shows that _ AC ≅ . Therefore, △ABC ≅ △DEF by . Use the HL Congruence Theorem to prove that the triangles are congruent. A Given: ∠P and ∠R are right angles.
