ABC is a right-angled triangle. Given that cos ⁡x =34 and that the length of the side adjacent to the angle x is 9 cm, work out the length of the hypotenuse.

d. x – 4.9 = 0.3 and x – 4.9 = –0.3

Step-by-step explanation:

Given,

The estimated weight of the pumpkin = 4.9 pounds,

Since, the weight of his pumpkin can be within 0.3 ounces,

Let x be the actual weight of the pumpkin,

⇒ Maximum estimated weight of the pumpkin = x + 0.3 ,

And, minimum estimated weight of the pumpkin = x - 0.3,

⇒ x + 0.3 = 4.9 and x - 0.3 = 4.9

⇒ x - 4.9 = - 0.3 and x - 4.9 = 0.3

⇒ Option d is correct.
