ANSWER=5.2
Step-by-step explanation
This triangle shows a example of the Pythagorean Theorem, which means the equation is gonna be
a^2+b^2=c^2
The variables a and b are the straight sides of the triangle, while the variable c is the curved side on the triangle, or what we are trying to find in this question.
Firstly let’s take the two sides that already have a number shown, also known in the Pythagorean Theorem as sides a and b.
2^2+4.8^2=c^2
Now we want to square the two given numbers to get the equation
4+23.04=c^2
Now we add the two given numbers that we have now squared to get the equation
27.04=c^2
The final step will now be to take the number (27.04) and square root it, which should give you the answer, 5.2
