Answer:
(-3/8/-(3/8) then you calculate -3/8*(-3/8) then its going to be - 3/-8*3/8 which equals -3/-3 and that becomes -(-3/3) then that becomes 3/3 and the ANSWER IS 1
Step-by-step explanation: Look at answer above.^^^
Answer:
1. x = 40°
2. 4x - 25 = 135°
3. x + 5 = 45°
Step-by-step explanation:
1.
<u><em>According to the figure and since m//n then </em></u>
<u><em>The two angles of measures (respectively) 4x - 25 and x + 5 are supplementary .</em></u>
Then
4x - 25 + (x + 5) = 180°
Then
5x - 20 = 180
Then
5x = 200
Then
x = 200/5
Then
x = 40°
……………………
2.
x = 40
Then
4x - 25 = 4(40) - 25 = 160 - 25 = 135°
…………………………………………………………
3.
x = 40
Then
x + 5 = 40 + 5 = 45°
Answer:
Step-by-step explanation:
<u>Perpendicular Bisector</u>
The bisector of a segment defined by points (x1,y1) and (x2,y2) must pass by the midpoint of the segment.
The midpoint (xm,ym) is calculated as follows:
The endpoints of the segment are (-3,-8) and (5,-4), thus the midpoint M is:
Midpoint: M(1,-6)
Let's find the slope of the given segment. The slope can be calculated with the formula:
If the bisector is also perpendicular, its slope m2 and the slope of the segment m1 must comply:
Solving for m2:
Once we have the slope -2 and the point through which our line must pass (1,-6), we compute the equation in its point-slope form:
