So a slope of a line can be perpendicular. So if the slope is a/b then the slope perpendicular to that is -b/a. PLEASE MARK AS BRAINLIEST!!
Move the decimal over 5 times when it's a positive interval notation:
200,000
660,000
m<1 = m<4 by vertical angles theorem
3x + 10 = 4x - 15
-1x = -25
x = 25
m<1 + m<7 = 180 if parallel alternate interior angles supplementary
3x + 10 + m<7 = 180
3(25) + 10 + m<7 = 180
75 + m<7 = 180
m<7 = 105°
Hope this helps! ;)
