On a hiking trip, antoine hiked for 3 hrs traveling 5.25 mi before he took a break for lunch. he then hiked for 3 more hrs, took a rest break, and hiked for 1 more hour. after lunch, antoine traveled twice as fast as he did before lunch. how many miles did he travel on his hiking trip

14 miles on the hiking trip

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
