A number, truncated to 1 decimal place, is equal to 15.4

Write down the lower and upper bounds of the number.

answer: i guess 105 degrees?

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

i those same problems in math and dont know how to do them
