The equation for line g is given by 5y=2x-20. suppose line g is parallel to like r and line e is perpendicular to line g. point (10,-8) lies on both line r and line e. write an equation for line e

5x + 2y = 34

Step-by-step explanation:

The desired line is perpendicular to 5y = 2x -20 and goes trhough point (10, -8).

General Approach

You can write the equation of a perpendicular line through (h, k) by ...

Then, you can put the equation in the form you desire.

This Problem

... 2(y+8) = -5(x-10) . . . . . coefficients swapped, negated; replacements made

... 2y + 16 = -5x +50 . . . . eliminate parentheses

... 5x +2y + 16 = 50 . . . . .add 5x

... 5x + 2y = 34 . . . . . . . .  subtract 16. This the equation in standard form.

the answer is c

hope this !

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
