Answer:
I believe the answer is D.
<span>1. </span><span>Well if the quotient is 45 ¼, the
divisor will depends on the dividend.
Since the dividend is not given, there it would be hard for us to tell what is
the divisor.
Because we only have the quotient, there are a lot of answers then if the
dividend is not given.
it can be that the divisor is 2 and the dividend is 90 ½ to be able to get 45 ¼
as an answer.
it’s hard to tell without identifying the dividend.</span>

Answer:
100°
Step-by-step explanation:
The relevant relation for angle x is ...
x = (AB +DE)/2
and for angle y, it is ...
y =(AC -DE)/2
Using the second relation to write an expression for DE, we have ...
DE = AC -2y
In the first equation, this lets us write ...
x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2
2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2
(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3
AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values
AC = 100°
(3x+3) + (4x + 2)
------------------------- = 13
2
13(2) = (3x+3) + (4x+2)
26 = 3x + 3 + 4x + 2
26 = 7x + 5
26-5 = 7x
21 = 7x
x = 21 ÷ 7
x = 3
