Find cos(−2835°) and sin(−2835°). identify the measure of the reference angle

Solution:

As per the question:

We need to find the values of:

Now, we know that:

Also

Now,

From the above eqn (1)  and (2):

Now the above respective values can be further calculated from eqns (3) and (4):

where

n = 8

only 10/60 isn't equivalent

hope this : )

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
