Check the picture below.
notice, both angles are lying on a flat-line, surely you'd know what "x" is then.
I don’t know about Question One, but I can do the other two.
Question Two:
Since the first one is 2 for 3000, you divide 3000/2 and get 1500. If you do the same for 4500/3 and 7500/5, you will find that 1500 is the answer to all of them. Each panel is 1500$. If you multiple 1500$ by 9, you will get 13,500$
Question 3:
To find each, you need to divide the total price by the number of hours. The first company is 128/5, making it 25.60$ per hour. The second company is 181/6, making it 30.17$ per hour. Finally, the third company is 195/8, making it 24.38$ per hour. The best deal would be the final one because it costs the least per hour.
The answer is A.
Angles 1 and 2 are congruent, therefore angle 2 = 122.
The sum of all three angles in a single triangle would be 180.
180 - 122 = 58
Therefore, each of the other angles have to be LESS than 58.
