If Angelica is 5 steps to the right of the classroom door and Brion is 12 steps to the left how many steps apart are they?

Angelica is 5 steps to the right while Brion is 12 steps to the left it is 17 steps because theyre going in the opposite directions :P

please give if you can

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
