All the angles make a full circle which needs to equal 360 degrees.

Add all the angles together to equal 360:

X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360

Combine like terms:

9x -30 = 360

Add 30 to both sides:

9x = 390

Divide both sides by 9:

X = 390/9

X = 43.3333. ( 43 and 1/3)

Answer:

x = 43 1/3 degrees.

Step-by-step explanation:

All these angles add up to 360 degrees , so we have:

x - 10 + 4x - 20 + 2x - 10 + x + 10 + x = 360

9x - 30 = 360

9x = 390

x = 390/9

= 43 1/3 degrees

\frac{7i}{3-11i}*\frac{3+11i}{3+11i}=\\
\frac{(7i)*(3+11i)}{3^2-(11i)^2}=\\
\frac{21i+77i^2}{9+121}=\\
\frac{21i-77}{130}=\\
\frac{-77+21i}{130}$

so it is the last option

pentagon [3]

He traveled 2080 miles after 4 hours. He covered 3640 miles in 7 hours with a constant speed, so we can calculate the speed: 3640/7=520 miles/hour. After 4 hours, he traveled 520*4=2080 miles.
