Primary succession occurred, followed by several secondary succession
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:
2
Step-by-step explanation:
Given two points on the line, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7 - -3)/(3 - -2)
= (7+3)/(3+2)
= 10/5
=2
Answer:
X=12
Step-by-step explanation:
2/3x-5=1/2x-3
2/3x=1/2x+2
2/3x-1/2x=2
(6)1/6x=2(6)
X=12
