Answer:
No
Step-by-step explanation:
Diameter= 180cm
Circumference of each table
= πD
= 180π cm
Each table can fit
= 180π ÷70
= 8 guests (nearest whole number)
Since there are 18 tables, total number of guests
= 8(18)
= 144 guests
Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.
Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.
If that was done,
Total circumference
= 180π(18)
= 10179 cm (5 s.f.)
Total number of people
= 10179 ÷70
= 145 people (3 s.f.)
This is incorrect.

Step-by-step explanation:
When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines () and () are parallel.
The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.

Answer:
The next step is to find the point on the circle which makes a tangent line that passes through the outside point.
Step-by-step explanation:
A tangent line to a circle is a line that touches the circle at exactly one point. You need two points to draw a line. You already have one point and the circle, then you need the other point, which lies on the circle. These two points have to lie on the same line. Notice that there are two possible tangent lines.
