The differences are that in the first equation it has an x and the other has a 3. The first equation is divided by x+3 while the other is divided by x-2
Volume (rectangular prism)=long x wide x hight
Data:
volume=2880 in³
Long=24 in
wide=10 in.
2880 in³=24 in * 10 in * higth
2880 in³=240 in² * hitgh
higth=2880 in³ / 240 in²
higth=12 in
Answer: the higth of the aquarium is 12 in.
Answer:
x = 44°
Step-by-step explanation:
The sum of the exterior angles of any polygon my be 360°, so just add all the angles up, and subtract this from 360°.
Given a pentagon with exterior angles: 102°, 47°, 34°, and 133° with the missing angle x°.
To find the missing angle, first write an equation representing the given rule:
102° + 47° + 34° + 133° + x° = 360°
(316°) + x° = 360°
316° + x° - 316° = 360° - 316°
x° = 44°.
This way, because the rule must be true, the missing angle with this value will satisfy this:
102° + 47° + 34° + 133° + <u>44°</u> = 360°
For this topic, here are some general angle rules for polygons:
- n is the number of sides
- 180° (n – 2) = sum of interior angles of any polygon.
- 180° (n – 2) / n = each interior angle of a regular polygon [all sides and or angles the same measure / congruent].
- 360° = sum of exterior angles of any polygon.
- 360° / n = each exterior angle of a regular polygon. [all sides and or angles the same measure / congruent].
