What is the slope of the line perpendicular to the line with equation 4x-5y+13=0
motikmotik

Answer:

m = - 5/4

Step-by-step explanation:

If two lines are perpendicular, their slopes are negative reciprocals, which means that their product is -1

We can write the equation

4*x - 5*y + 13  = 0

as:      5*y  =  4*x  + 13      or    

y  = (4/5)*x  + 13        (1)

Equation (1) is the equation of a straight line in its slope point form, 4/5 is the slope, according to this  the slope of a perpendicular line is

-5/4

The measure of one angle of a right angle is 50 more then the measure of the smallest angle
Nataly_w [17]

Answer:

70° and 20°

Step-by-step explanation:

let x be the measure of one angle then x + 50 is the measure of the other angle, thus

x + 50 + x = 90

2x + 50 = 90 ( subtract 50 from both sides )

2x = 40 ( divide both sides by 2 )

x = 20

The smallest angle is 20° and the other angle is 20 + 50 = 70°
