Find m angle t, rounded to the nearest degree

Using the law of cosine:

Cos (Angle) = Adjacent leg / hypotenuse

Cos (Angle) = 4/17

Angle = Arccos(4/17)

Angle = 76.39

Rounded to nearest degree = 76 degrees.

idk sry

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
