Hey there!!
Steps to get into equation which is perpendicular:
- The slope of a perpendicular line is always negative reciprocal.
- Take the point and get that into point-slope form.
- y - y = m ( x - x )
- Convert this equation into slope-intercept form.
'm' is the slope.
We have the slope as 1/3
The perpendicular slope would be -3.
Point slope:
The point = (-2,2)
y - 2 = -3( x - (-2) )
y - 2 = -3(x+2)
y - 2 = -3x -6
Adding 2 on both sides:
y = -3x - 4
<em>Hence, the equation would be : </em>
<u><em>y = -3x - 4 </em></u>
Hope it helps!
Answer:
C) 48.3
Step-by-step explanation:
The lines are parallel, meaning that when the third line is intersecting them both, the angles formed will be exactly the same. The top angle that is to the right is 25°, meaning that he bottom angle to the left is 25°. All that is left is to find the last two angles in order to find out what the answer to the equation is. The 25° angle is next to a triangle causing the lines to be flat, or 180°.
180 - 25 = 155
That means the bottom angle to the right is 155. In order to find x, subtract 10 and divide by 3.
3x + 10 - 10 = 155 - 10
3x = 135
3x/3 = 135/3
x = 48.3
