Starting 130 feet away, a person on bicycle rides toward a checkpoint and then passes it. the rider is traveling at a constant of 25 feet per second. the distance the bicycle and the checkpoint is given by the equation d=|130-25t|. at what times is the bike 15 feet away from the checkpoint? 4.6sec and 9.2 sec 2.9sec and 5.8 sec 4.6sec and 5.8 sec 2.9sec and 3.3 sec some with correct answer!

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
