Answer: 20inch
Step-by-step explanation:
Using the Pythagoras theorem:-
25^2 = 15^2 + x^2 where x = the width of the screen.
625 = 225 + x^2
x = √(625 - 225) = √400
= = 20 ins
Question:
On a coordinate plane, a line goes through (negative 3, 2) and (0, 1). A point is at (3, 4). What is the equation of the line that is perpendicular to the given line and passes through the point (3, 4)? y = –One-thirdx + 5 y = –One-thirdx + 3 y = 3x + 2 y = 3x − 5
Answer:
Option D:
is the equation of the line
Explanation:
It is given that the line passes through the points
and 
We shall find the equation of the line that passes through the points
and 
Slope 

Also, it is given that the line is perpendicular to the line having slope 
Since, we know that if two lines are perpendicular, then the product of the two slope is equal to -1.
Thus, we have,



Thus, the slope of the line is
and passes through the point 
Now, we shall find the equation of the line using the formula,

Thus, we have,



Thus, the equation of the line is 
Hence, Option D is the correct answer.

Answer:
98°
Step-by-step explanation:
Supplementary angles are two angles whose sum is 180 degrees.
180° - 82° = 98°
