An angle is formed by two rays with a common endpoint. The endpoint is the vertex. And the two rays are the sides
Example name - PQR Q is the certex
The x coordinates are 1 and 4
Lateral surface are = 2( 1/2 x 11 x 11.9) + 2( 1/2 x 9 x 12.3)
Lateral surface area = 130.9 + 110.7 = 241.6 ft²
Answer: 241.6 ft² (Answer C)
Our goal is to get x by itself to find the value so
First we multiply 10 to both sides
S - 31 = 60
Then add 31 to both sides to get a
s = 91
Hope this helps!
B.$2.55 i think but just check
