Answer:
8
Step-by-step explanation:
The Pythagorean theorem tells you of the relation ...
x² + 6² = 10² . . . . . . . . . squares of sides total to the square of hypotenuse
x² = 100 -36 = 64 . . . . . subtract 6²
x = √64 = 8 . . . . . . . . . . square root
The length of side x is 8 units.

Step-by-step explanation:
Answer:
sinΘ =
Step-by-step explanation:
using the identity
sin²x + cos²x = 1 ( subtract cos²x from both sides )
sin²x = 1 - cos²x ( take square root of both sides )
sinx = ±
given
cosΘ = - , then
sinΘ = ±
= ±
= ±
= ±
since Θ is in quadrant II where sinΘ > 0 , then
sinΘ =
