Step-by-step explanation:
Given:
Lengths of edges of triangle:
feet
feet
feet
Perimeter of the triangle= Sum of all sides = 
feet
On simplifying by adding like terms:
Perimeter of triangle = 
feet
Given 
∴ Perimeter of triangle = 
= 40 feet

Answer:
<h3>
∠XYZ = 102</h3><h3>
</h3>
Step-by-step explanation:
<u>1st step is to solve x from ΔWXY</u>
∠W + ∠X + ∠Y = 180
where ∠W = 5x + 2
∠X = 7x + 4
∠Y = 180 - (15x - 18)
= 198 - 15x
now plugin values into the equation:
5x + 2 + 7x + 4 + 198 - 15x = 180
combine similar terms:
5x + 7x - 15x = 180 - 2 - 4 - 198
simplify:
-3x = -24
x = -24 / -3
x = 8
<u>2nd step is to substitute x = 8 into ∠XYZ</u>
∠XYZ = 15x - 18
∠XYZ = 15(8) - 18
∠XYZ = 102
Answer: 10 × 3 + 4 + 5 × 2 + 1 + 3 × 100 = 345
