Step-by-step explanation:

If you know tangent of theta is 5/3 and it is in the 3rd quadrant, then you know the sides will be going in the negative direction and the real values of the sides would be -5/-3. You can use pythagorean theorem to figure out that the hypotenuse would be sqrt(5^2+3^2) = sqrt(34). Then you can use soh cah toa: sin = opp/hyp, cos=adj/hyp tan = opp/adj. You know that opp = -5, adj = -3, and hyp = sqrt(34) For cosine theta, it would be -3/sqrt(34) and csc is just 1/sin so csc would be hyp/opp = sqrt(34)/-5.

can someone tell me the answer to this please..?

Answers

Answer:

x=8

this is because you do 57+89=146

and then you do 180-146 because a triangle adds up to 180.

this gives you 34

so the value of 5x-6=34

add the 6 onto 34 which gets rid of the -6 ans fives you the answer of 40

After that yoy divide 40 by 5 which gives you the value of x which is 8
