I need help and please write out the answer​

(2/9) = 77°

Step-by-step explanation:

In your calculator, depending on what type you have, there should be a button that says 2nd. There should also be a button that reads cos, which is cosine.

We want inverse cosine, so click 2nd then cos. This should be inverse cos, .

Your calculator should have (

So type 2/9 in the parentheses because is the same as 2 divided by 9.

So it should be (2/9) in your calculator. Press enter and you should have 77.16041161.

Here are some scientific calculators and where to find their buttons:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
