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

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
