The angle whose sine is 0.39581 is 23.32 degrees. This is calculated by obtaining the arcsine of the value given above. The sine function is one of the basic functions in trigonometry together with cosine, tangent, cosecant,secant and cotangent.
2/3 meters would be a reasonable estimate.
Answer:
Option A -
is the standard form of the equation.
Step-by-step explanation:
Given : Linear equation - 
To convert into the standard form.
Standard form of the equation is in form Ax+By=C
So to convert this equation into the standard form we have to multiply both side of the equation by -1, so that the value for A is positive.
After multiplying by -1 the form is

is the standard form of the equation.
Therefore, Option A is correct.
So the 3x means three times then u multiply by three
