Answer:
hhhhhhhhhhhhhhhhhhh
Step-by-step explanation:
hhhhhhhhhhhh
You would need to use the pythagorean theorum which is would be 8 squared +x squared = 15 squared
Just as in base 10, when you get to the highest single digit and add 1, you carry into the next higher place value. If your number were 129 in base 10, the next number in sequence is 130. If your number were 1399, the next number in sequence would be 1400.

In the given diagram, the length of the side marked x is 21.34
<h3>Trigonometry </h3>
From the question, we are to determine the value of the side marked x
In the given diagram,
Hypotenuse = x
Adjacent = 15
Included angle = 49°
Using SOH CAH TOA
We can write that,
cos 49° = 14 / x
∴ x = 14 / cos 49°
x = 21.34
Hence, the length of the side marked x is 21.34.
