I need to convert 139° 10′ to radian. In order to do that I need to multiply with π/180 and simplify. How do I do this?

139° 10′ This is degree minutes. Convert the minutes to decimal by dividing the minutes by 60.

10/60 = 0.167

So 139° 10′ = 139.167 degrees.

Now convert to radians:

139.167 x pi/180 = 2.429 radians

The answer may be slightly different depending on the rounding of everything.

what is the question here

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
