Answer and explanation:
Given : Equations
1) 
2) 
To find : Tell whether the following equations are true or false. Then, explain your reasoning.
Solution :
Equation means when left hand side and right hand side of the equation is same.
1) 
Take LHS,

Same term with opposite sign cancel each other or sum is zero,


Therefore, Yes, it is true as it satisfy definition of equation.
2) 
Take LHS,

Same term with opposite sign cancel each other or sum is zero,

Answer:
12.8 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between angles and sides of a right triangle. Here, you have the side opposite the given 70° angle, and you want to find the hypotenuse. The appropriate relation is ...
Sin = Opposite/Hypotenuse
Solving for the hypotenuse, we get ...
Hypotenuse = Opposite/Sin
x = (12 cm)/sin(70°) ≈ 12.77 cm
x ≈ 12.8 cm
