Answer:

7 cm

To find the measure of the side, simply divide the perimeter by 3. This is because a triangle has 3 sides.

21 ÷ 3 = 7

What is the measure of <8
True [87]
Answers:
Angle 8: 125
Angle 3: 55
The relationship between angle 1 and 5: corresponding angles.

Why? Angle 8 is equal to 180-55 so 125
Angle 3 is a corresponding angle to the angle labeled 55 so it’s 55. For the last one it is just the rule of law.

Hope this helps :D
