Answer:
4.5 ≤x<4.55
Step-by-step explanation:
for whole number
It has to be 4.5 or greater to round to 5 on the low end
It has to be less than 5.5 to round to 5 on the high end
for tenths
If has to be 4.45 or greater to round to 4.5 on the low end
It has to be less than 4.55 to round to 4.5
We take the more restrictive limits to define the number
The number must be between
4.5 ≤x<4.55

Step-by-step explanation:
<h3>Q13</h3>
The greater the angle the greater the opposite side
<u>Sides in ascending order:</u>
- AB = 17, AC = 18, BC = 21
<u>Angles in same order</u>
<h3>Q14</h3>
<u>As above, sides in ascending order:</u>
- AB = 15, AC = 16, BC = 17
<u>Angles in same order</u>
<h3>Q15</h3>
<u>Exterior angle equals to sum of non-adjacent interior angles</u>
- 142° = x + 66°
- x = 142° - 66°
- x = 76°
<h3>Q16</h3>
<u>Same subject and isosceles triangle:</u>
- x + x = 158°
- 2x = 158°
- x = 79°
<h3>Q17</h3>
<u>Same subject</u>
- m∠QSR = m∠QPS + m∠PQS
- 2x = x + m∠PQS
- m∠PQS = 2x - x
- m∠PQS = x
ΔPQS has two angles with the measure of x, hence their opposite sides are congruent and the triangle is isosceles
Solution: The statement is false, but the converse is true.
Answer:
<em>If a whole number is even, then the number is divisible by 4</em>.
This statement is false because there are even numbers smaller than 4 that are not divisible by 4.
The converse of the statement is <em>If a number is divisible by 4, then the number is even</em>.
This statement is true because all multiples of 4 are even.
