Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)
Answer:
it ix 23 then 43
Step-by-step explanation:
3 divided by 8 = 0.375
0.375 x 100 = 37.5%
37.5% is closest to 38%
No.
Perpendicular lines are lines that intersect at a 90° angle.
If two lines are perpendicular, they create four 90° angles.
However, for two lines to intersect, they do not necessarily have to intersect at a 90° angle.
<em>All roses are flowers, but not all flowers are roses.</em>
<em>All perpendicular lines are intersecting lines, but not all intersecting lines are perpendicular.</em>
