The sum of the interior angles of a triangle is always 180 degrees. Thus,
the sum of 31, x+4 and 3x+9 must be 180.
31 + x + 4 + 3x + 9 = 180, or 44 + 4x = 180
While it's not necessary, y ou could reduce this equation before solving for x:
11 + x = 45. Then x = 34 degrees.
The three angles are then:
31
34+4 = 38
3(34) + 9 = 111
Check: show that 31+38+111 = 180 (degrees)

Answer:
360°
Step-by-step explanation:
The sum of exterior angles of any convex polygon is 360°.
To find this you would do 800 + 15x where x is the amount of years.
For 9 years it would be 800 + 15(9) which is 800 + 135.
At the end of 9 years, the apartment's rent would be $935. I hope that's utilities included because... yikes...
Answer:
C. 50
Step-by-step explanation:
Answer:
945 ways
Step-by-step explanation:
<u>Total</u>
- Number of Appetizers = 7
- Number of main courses = 9
- Number of desserts =5
<u>Required Selection</u>
- Number of Appetizers = 2
- Number of main courses = 8
- Number of desserts =4
2 Appetizers out of 7 can be selected in 
ways
8 main courses out of 9 can be selected in 
ways
4 desserts out of 5 can be selected in 
ways
Therefore, the number of ways this can be done
=945 ways
