5x+ 10= -4x -17
⇒ 5x+ 4x= -17 -10
⇒ 9x= -27
⇒ x= -27/9
⇒ x= -3
Final answer: x=-3~

Sum of interior angles of a quadrilateral is 360°
- 110° + 130° + x + x - 3° = 360°
- 2x = 360° - 237°
- 2x = 123°
- x = 61.5°
(18)
Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
- 2*90° + 2x + 2(x + 22°) = 720°
- 90° + x + x + 22° = 360°
- 2x = 360° - 112°
- 2x = 248°
- x = 124°

Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.
The range is Max - Min = 299 - 0 = 299
Divide this range over 10 to get 299/10 = 29.9 which rounds to 30
We'll need about 30 intervals if we want intervals of width 10
Answer: D) 25 or more
Surface Area of cylinder = 8195.4 inches^2
Step-by-step explanation:
we are given:
Diameter of cylinder = 30 inches
Height of cylinder = 72 inches
We need to find:
Surface area of cylinder = ?
The formula used is:
We know radius = diameter/2
so, radius = 30/2 = 15 inches
putting values:
So, Surface Area of cylinder = 8195.4 inches^2
