1. In the figure, m DE=124, and M BC=36. The diagram is not drawn to scale. What is m A? A) 44* B) 62* C) 80* D) 88* please help

Anuta_ua [19.1K]

The relation between arc length and exterior angle is given in the figure.

Now we are given far arc length as DE =124

We are given near arc length as BC = 36

So plugging in the formula to find measure of angle A:

$angle A=\frac{far arc-near arc}{2}$

$angle A=\frac{124-36}{2}$

$angle A=\frac{88}{2}$

Angle A = 44 degrees

Answer : A) 44 degree

Mila [183]

Answer:

The profit is $24

Step-by-step explanation:

Step one:

given the expression for the profit made as

$1.25p-0.75p,$

we are told that p is the number of pens, hence for p= 48 by substituting into the expression we can find the profit as

Step two:

Profit= 1.25p-0.75p,

Profit= 1.25(48)-0.75(48),

Profit= 60-36

Profit=24
