Use the three steps to solve the problem. express the answers using decimals.

it took john 12 hours riding his bike to make the round trip to his uncle's. if he averaged 20 mph out and 30 mph back, how long did he travel each way? (round answer to nearest tenth.)

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

the answer

b. they are parallel and will never intersect.
