Answer:
(Equation 1)
(Equation 2)
We can substitute Equation 1 into Equation 2 like so:
Subtract x from both sides:
Divide both sides by 2:
.
Substitute into Equation 1 to find y:

-3x=-57
x=19
Answer:
H is 2.2cm.
Step-by-step explanation:
- A pentagon is a polygon with 5 sides.
- If all the sides are equal it is a regular polygon otherwise it is Irregular.
The Perimeter of the given pentagon =10.5cm
Four sides of Length Hcm are equal
The length of the fifth side = 1.7cm
Therefore: The sum of all the sides= 4H+1.7
4H+1.7=10.5
4H=10.5-1.7
4H=8.8
Divide both sides by 4
H=2.2 cm
The value of H is 2.2cm.
