Answer:
A. Definition of angle bisector
Step-by-step explanation:
Given that ΔABC is an isosceles triangle where AB = BC, and that BD bisects ∠ABC, then by the definition of angle bisection of ∠ABC, we have;
m∠ABD = m∠CBD
The correct option is option A. Definition of angle bisector
<em>Also, given that ΔABC is an isosceles triangle and BD is the angle bisector of ∠ABC, we get;</em>
<em>AD = CD and BD = BD</em>
<em>We can therefore, also find that ΔABD ≅ ΔCBD by Side Side Side (SSS) rule of congruency</em>
Answer:
take 1/4 to the other side since 1/2 and 1/4 are like terms then solve for X getting 16/5 as the answer
Have a wonderful time
Answer:
9 to the 7th power
Step-by-step explanation:
Answer:
3x^2-4x+12
Step-by-step explanation:
x(2x+3)+(x-3)(x-4)
2x^2+3x+x^2-3x-4x+12
2x^2+x^2+3x-3x-4x+12
3x^2-4x+12
Answer:
x = 18
Step-by-step explanation:
Given two intersecting chords inside a circle, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
7x = 21 × 6 = 126 ( divide both sides by 7 )
x = 18
