Basically, we need to plug in the given values for the variables

and

into the given expression

. First off, we can plug in all the given values into the expression, giving us

. Now, perform the operations on the inside of the parentheses. Doing this, we get

. Now, we use the distributive property to simplify. This gives us

. Finally, when we add the two numbers, we get

. Hope this helped!

<u>2. </u><u>find</u><u> </u><u>cos Ф, sin Ф, tan Ф</u>
cos Ф = 5 / 13
Ф = 67.38
sin Ф = 12 / 13
Ф = 67.38
tan Ф = 12 / 5
Ф = 67.38
-----------------------
<u>3. find sin β, cos β, tan β</u>
sin <u>β</u> = 4 / 5
<u>β</u> = 53.13
cos <u>β</u> = 3 / 5
<u>β</u> = 53.13
tan <u>β</u> = 4 / 3
<u>β</u> = 53.13
