Answer: 7
Step-by-step explanation:
As tangents drawn from a common external point to a circle are congruent,
- 8x - 7 = 6x + 7
- 2x - 7 = 7 [subtract 2x from both sides]
- 2x = 14 [add 7 to both sides]
- x = 7 [divide both sides by 2]
Answer:
18
Step-by-step explanation:
You plug in 2 hours as your x value. You get 4(2) + 10 = 18.
In the first quadrant, 0-90 degrees, the angle whose cotangent is is 45 degrees. The only other quadrant where cot theta is 1 is 3rd quadrant.
The 2 angles are 45 and 180+45 = 225 degrees
Answer 45 , 225 degrees.
