Answer:
Step-by-step explanation:
In Δ ABC & ΔADC
AC bisect ∠BCD given
∠ACB ≅ ∠ACB AC bisect ∠BCD
DC ⊥ AD Given
BC ⊥ AB Given
∠ABC = ∠ADC Right angles are ≅
AC ≅ AC Common to both triangle ΔABC & ΔADC
ΔABC ≅ ΔADC AAS congruent
BC ≅ DC CPCT
Answer:
A.
Step-by-step explanation:
A negative of the same value added to positive always gives you 0
negative is inverse of positive
Answer:
d
Step-by-step explanation:
Since DF = EF then the triangle is isosceles with base angle being congruent, that is
∠ D = ∠ E , then
∠ D =
=
= 23.5°
