Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

(x + 5) + (2x + 7)  = 90\\ 2x + x + 5 + 7  = 90 \\ 3x + 12  = 90 \\ 3x  = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26

Sub x in

(x + 5) \\ 26 + 5 = 31

and

(2 \times 26 + 7) \\  = 52 + 7 \\  = 59

pickupchik [31]

Answer:

Value of the stock traded was $5200.

Step-by-step explanation:

In this question it is given that trading company charges commission of $10 per trade or transaction plus $.025 per dollar value of stock.We have to calculate the value of stock we traded if total commission (commission on trade value + commission on trade) is $140.

Let the value of stock traded was $x.

Then commission on value of the stock = x×.025

Commission on transaction = $10

Total commission = 140 = ( .025x + 10)

⇒.025x = 140-10 = 130

x = 130÷.025 = $5200

So the value of the stock = $5200
