The Pythagorean theorem tells you the other leg is
... √(c² - a²) = √(4.2² -2.9²) = √9.23 ≈ 3.038 ≈ 3.0
_____

No, it would be 180.0 , since you are multiplying the small amount by a large amount that is not negative.
Answer:
I hope you have options. and if you can find these answers in the options it will be good. cos I'm not so sure
11. 9
12. 8.6 or 9 approximately
13. 56 degree
14. 33 degree
Here’s your answer! Have a good day
Using the Pythagorean theorem:
47 ^2 = 11^2 + x^2
2209 = 121 + x^2
Subtract 131 from both sides
2088 = x^2
Take the square root of both sides
X = sqrt(2088)
Simplify
X = 6sqrt(58)
