This is a lot of calculation.

So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.

Now you just add up all angles and simplify the equation:

900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)

900 = <span>25x + 225

Now it's just regular algebra equation. You can solve for x:

675 = 25x

x = </span>27

So the value of x is 27

Ursula and her friends are playing hoop rolling. Ursula rolls a large hoop along the ground. The hoop rotates through an angle o

Karo-lina-s [1.5K]

1 revolution = 360 degrees
3/2pi = 1 second
1 revolution = 2pi radius
3/2pi (360/2pi)= 3/2pi (180/pi)=270 degree sec.

Austin got a raise. Their hourly wage was increased from $18.00 to $20.50. What was the percent increase in Austin’s wage to the

agasfer [191]

Answer:

option 3)

14% approx

Step-by-step explanation:

Given data

Initial= $18.00

final =$20.50

% increase= final - initial/initia *100

% increase= 20.50-18.0/18*100

% increase=2.5/18*100

% increase=0.138*100

% increase=13.8%

Hence the increase is 13.8%

=14% approx
