Answer:
12
Step-by-step explanation:
we use Pythagoras law
√13^2-5^2
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m of AB using the slope formula
m =
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)
m = = = 0
A line with a slope of zero is a horizontal line, parallel to the x- axis.
Thus a line perpendicular to AB is a vertical line parallel to the y- axis.
The slope of a vertical line is undefined
Answer:
csc (- Ф) = -29/20
Step-by-step explanation:
We know that:
csc Ф = 1/ sinФ ................. equation 1
csc (- Ф) = - csc Ф .............equation 2
Given that:
sin Ф = 20/29
Using equation 1:
csc Ф = 1/ (20/29)
csc Ф = 29/20
using equation 2:
csc (-Ф) = - csc Ф = -29/20
