Without using calculator find :<br> cos(225) sin(315) + sin( –270) tan(405)
Ronch [10]

Answer:

1.5

Step-by-step explanation:

225° bisects Q III

315° bisects Q IV

-270° = 90°

405° = 45° bisects Q I

cos(225) sin(315) + sin( –270) tan(405) = ?

      (-½√2)(-½√2) + 1(1) = ?

                          0.5 + 1 = 1.5

Write and solve an equation to find the number<br><br> six times the sum of a number and 15 is -42
Mumz [18]

Hey there! I'm happy to help!

Sum means to add. Let's call our number n.

n+15

We multiply this whole thing by 6.

6(n+15)

And this is -42.

6(n+15)=-42

We use distributive property to undo the parentheses.

6n+90=-42

We subtract 90 from both sides.

6n=-132

We divide both sides by 6.

n=-22.

Have a wonderful day! :D
