Please help me. Thank you. There is a keypad to the right of the locked door. Hanging up next to it is a clipboard with a basketball diagram. This must be the way to figure out which locker the keycard is in.
What is the measure of ∠B? The keycard is supposed to be in the locker with that number. *

answer: ok

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

just get this app called photo math it should be able to do those
