The three angles create a triangle. The sum of the angles of a triangle is always 180°.
Solving for x,
45° + 35° + x = 180°
x = 100°
The mnemonic SOH CAH TOA helps you remember that
... Sin = Opposite/Hypotenuse
The side opposite angle K is marked with length 5. The hypotenuse KM is marked with length 10. Using the above relationship ...
... sin(∠K) = 5/10 = 1/2
The first choice is appropriate: 
Step-by-step explanation:





Answer:
84
Step-by-step explanation:
x12
Simplify ———
x14
Dividing exponential expressions :
1.1 x12 divided by x14 = x(12 - 14) = x(-2) = 1/x2
Final result :
1
——
x2
