Answer:
351°
Step-by-step explanation:
-369° + 360° = -9°. This is in Quadrant IV. If you want a reference angle in Quadrant I, find the positive angle between 0 and 360° that has the same terminal point at does -9°. It is 360° - 9° = 351°
Answer:
y = 90°
Step-by-step explanation:
- 110° is the measure of exterior angle of bigger triangle.
- -> (x + x) + 70° = 110° (By exterior angle theorem)
- y is the measure of exterior angle of smaller triangle.
- -> y = x + 70° (By exterior angle theorem)
Answer:
(5x+1)(x - 2)
Step-by-step explanation:
Answer:
- shared short side: 10x +6
- shared long side: 8x +6
Step-by-step explanation:
The factors of the given polynomial are (2x+1) and (x+1). We presume these are the side lengths of each rectangular plot. If the short side (x+1) was common, then the perimeter of the combined lot is ...
4(2x+1) +2(x +1) = 10x +6 . . . units of fence for short side common
If the long side (2x+1) was common, then the perimeter of the combined lot is ...
4(x+1) +2(2x+1) = 8x +6 . . . units of fence for long side common
