Answer:
A) 45 degrees
Step-by-step explanation:
<span>Consider a angle â BAC and the point D on its defector
Assume that DB is perpendicular to AB and DC is perpendicular to AC.
Lets prove DB and DC are congruent (that is point D is equidistant from sides of an angle â BAC
Proof
Consider triangles ΔADB and ΔADC
Both are right angle, â ABD= â ACD=90 degree
They have congruent acute angle â BAD and â CAD( since AD is angle bisector)
They share hypotenuse AD
therefore these right angle are congruent by two angle and sides and, therefore, their sides DB and DC are congruent too, as luing across congruent angles</span>
Answer:
75c-180
420 for 8 customers
Step-by-step explanation:
Her tools cost her 180
-180
she makes 75 per customer
75c
She will make
75c-180
She gets 8 customers
75(8)-180
600-180
420
