Answer:
x ≈ 5.3
Step-by-step explanation:
a²+b²=c²
c is always the hypotenuse in a right angle triangle.
6² + x² = 8²
36 + x² = 64
64 - 36 = 28
x² = 28
x = √28
Use calculator from here.
√28 = 5.29150262213
5.29150262213 ≈ 5.3
Because the number after 2, which is 9, is greater than 5, the nearest tenth is 5.3, not 5.2.
