∠1and ∠2 are a linear pair, and ∠2 and ∠3 are vertical angles. m∠1=(3y+10)∘ and m∠3=(5y−30)∘. What is m∠2?

Step-by-step explanation:

It is given that ∠1 and ∠2 are a linear pair. So, there sum is 180 degrees.

   ...(1)

∠2 and ∠3 are vertical angles. So, both are equal.

    ...(2)

From (1) and (2), we get

Substitute and in the above equation.

Divide both sides by 8.

The value of y is 25.

Using equation (2), we get

Substitute y=25.

Therefore, .

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
