Question

Which expression shows the length, BC, of the base of the stand?

Answer 1

9 divided by sin 70 degrees
9 divided by cot 70 degrees
9 cot 70°
9 cos 70°

Answer 2

I think it's the 3rd one

Answer 3

We see that it is a right triangle lets draw this out...



Since we know of the adjacent as well as the opposite we would use the trig ratio tan....

\(\Huge{\tan(70)=\frac{9}{x}}\)

Now to solve for x we would have to divide 9 by tan...

\(\Huge{9 \div \tan(70)=x}\)

Answer 4

Ooo wait thats not one of the options one sec

Answer 5

Okiiee

Answer 6

Alrighty.

\(\Huge{9 \div \tan(70) = 9 \cot(70)}\)

Answer 7

Basically it is the same process but a different format...
