The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
Given:
The equation of given line is

A line is perpendicular to the given line and passes through the point (9,5).
To find:
The equation of the perpendicular line.
Solution:
We have,

On comparing this equation with slope intercept form
, we get

It means, the slope of the given line is 3.
The product of slopes of two perpendicular lines is -1.



Point slope form of a line is

Where, m is the slope.
The slope of perpendicular line is
and it passes through the point (9,5). So the equation of the line is



Adding 5 on both sides, we get


Therefore, the equation of required line is
.
Answer:
Final answer is 13.
Step-by-step explanation:
Given expression is
-k+h+kh
We also have been given values of h and k as:
k=-5 h=-2
to simplify the given expression, we just need to plug the given values of k=-5 and h=-2 into -k+h+kh
-k+h+kh







Hence final answer is 13.
