jarptica [38.1K]

Answer:

tan 5π/24.

Step-by-step explanation:

We use the identity:

tan (A - B) =   (tan A - tan B) / (1 + tan A tan B)

so the first expression simplifies to

tan ( π/3 -  π/8)

= tan 5π/24.

Someone help :(( thank youuuu so much if u do
VMariaS [17]

Answer:

-10

Step-by-step explanation:

The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.
