Please Help! ASAP! 45 points and Brainliest! The picture below shows a right-triangle-shaped charging stand for a gaming system: Which expression shows the length, BC, of the base of the stand? A) 9 divided by sin 70 degrees B) 9 divided by cot 70 degrees C) 9 cot 70° D) 9 cos 70°

BC = 9 cot 70

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp/ adj

tan 70 = 9/BC

BC tan 70 = 9

BC = 9/ tan 70

We know cot = 1/ tan

BC = 9 cot 70

54

step-by-step explanation:

6x9

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
