∠A and \angle B∠B are complementary angles. If m\angle A=(4x+6)^{\circ}∠A=(4x+6) ∘
and m\angle B=(4x-4)^{\circ}∠B=(4x−4)
∘
, then find the measure of \angle A∠A.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

the answer will be b x² +x-1

step-by-step explanation:

3+3+3+2*2*2+29*12 = 365

step-by-step explanation:

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
