Answer: 6
Step-by-step explanation:
From the information provided
adjacent = 8 hypotenuse = 10
opposite =?
Let opposite = x
Using the pythagoras theorem
opp² + adj² = hyp²
x² + 8² = 10²
x² + 64 = 100
subtract 64 from bothside
x²+ 64-64 = 100 - 64
x² = 36
Take the square root of bothside
√x² =√36
x = 6
