Either, The first one or the third one.
Unit rate = 20/4 = 5 m/s
hope it helps
First. distribute and multiply the the 4 to the 3^2 and the -5
so then it becomes 21+ 36 - 20
second. add and subtract that
answer is: 37
The given convex polygon has 7 sides
Hence its sum of interior angles is given by the formula , (number of sides-2)x180°
=> (7-2) x 180°
=> 5 x 180°
=> 900°
The sum of all angles must be equal to 900°
The given six angles are :
139°,126°,106°,129°,141°,112° , x°
=> 139+126+106+129+141+112+x = 900°
=> 753 + x = 900
=> x = 900-753
=> x = 147°
Hence 147° is the required answer.
