Answer:
(5x+12) (5x-12)
Step-by-step explanation:
Use the difference of squares fromula. 
Where a = 5x and b =12.
The angle RAT which is made with AR and AT line and shown in the figure of protector, measures 30 degrees.
<h3>How to measure the angle in protector?</h3>
Protector is the most useful device to measure the angle between two lines. To measure the angle between two lines using the protector following steps is followed:
- Place the protector center point at the vertex of unknown angle.
- One side of angle should be place at 0 mark line of this device.
- Other side of angle will be equal to the angle shown in protector on that line.
In the given figure, The angle Between AR and AT line is 30 degrees shown in protector.
Thus, the angle RAT which is made with AR and AT line and shown in the figure of protector, measures 30 degrees.

Answer:
105 square feet
Step-by-step explanation:
First of all, find the area of the rectangle (length x width). 7*12 = 84. Now, find the area of the triangle [(base x height)/2]. 6*7 = 42. 42/2 = 21.
Add both of these areas together: 84 + 21 = 105. The area is 105 square feet.
