Answer:
perimeter = 40 feet
Step-by-step explanation:
side^2 = 100
side = 10
perimeter = 10 x 4 =40
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A = 
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A = 
= 
= 
≈ 43.52 cm² ( to 2 dec. places )

Answer:
1. 135°
2. 62°
3. 148°
4. 180-x
Step-by-step explanation:
Supplementary angles are two angles that add to 180 degrees (a straight line).
Therefore, subtract the angle measure they give you from 180.
Hope this helps!
