The value of the hypotenuse is 69.77 meters.
Step-by-step explanation:
To determine, in triangle RG, the value of its hypotenuse if its sides measure 63 meters and 30 meters, the following calculation must be performed, applying the Pythagorean theorem:
63 ^ 2 + 30 ^ 2 = X ^ 2
3969 + 900 = X ^ 2
√ 4869 = X
69.77 = X
Therefore, the value of the hypotenuse is 69.77 meters.
