is given by the line integral

where

The integral is then


No, they are both incorrect by my understanding of your question use the Pythagorean theorem a^2 + b^2 =c^, therefore, 7^2 +x^2 = 13^2 or 49+x=169 then solve normally 169-49=120 √120 =5
The answer is 5
Answer:
24
Step-by-step explanation:
6+8=14 14+10=24
X+x+54=180
2x+54=180
2x=126
x=63
63+54=117
one angle is 63, the other is 117
