Answer:
Perimeter : 22.81 to the nearest hundredths
Area: 24 square units
Step-by-step explanation:
The vertices of ∆ABC are located at A(-2, 2), B(6, 2), and C(0, 8).
The perimeter is the distance around the figure.
Use the distance formula to find the side lengths of the triangle and add them up.

Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
