Perpendicular lines have slopes that are opposite signs and reciprocals.
Example: If one line has a slope of 5/3, then the perpendicular slope is -3/5.
In your case, your first line has a slope of -1/5. The perpendicular slope will be positive and will be 5/1.
The slope of a line perpendicular to the given one is 5.
1)
( 2.1•10000)+(6.7•100000)=21000+670000=691000
2)(8.3•1000000)-(2•1000000)=8300000+2000000=10300000
But i couldn’t explain third one
Hope this helps
Her totals sales were "x", now, if she sold "x", and made a 30% of "x" which is 1800, that simply means, "x" is the 100%
solve for "x"

Line segment BD is the diameter of Circle A. It is also the hypotenuse of the right triangle found inside circle A.
angle C = 90°
angle D = 54°/ 2 = 27°
angle B = 180° - 90° - 27° = 63°
The <span>measure of ∡DBC is 63</span>°
