Find the value of x.

x= 30°

Step-by-step explanation:

The shape is irregular, and it has 5 angles, and the formula for finding a n-sided polygon

is (n-2)180°. To get the total angle, (5-2)180°=3×180°=540°. X°+4x°+4x°+135°+135°=540° ; 9x°+270°=540° ; 9x°=540°-270° ; 9X°=270° therefore, X=270°÷9= 30°•

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

i believe the answer is 323 ft
