2x + 5 = 2x - 8
Add 8 to each side
2x + 13 = 2x
Subtract 2x from each side
13 = 0 isnt true.
C. No Solution.
Answer:
If a=A and B=b then the answer is C.-5
Answer:
In this triangle, the product of sin B and tan C is c/a or cos B, and the product of sin C and tan B is b/a cos C. We determine these as follows:
sin B tan C = b/a (c/b) = c/a
sin C tan B = c/a (b/c) = b/a
Hope this answers the question. Have a nice day.
Step-by-step explanation:
DONT NOW AM NO SURE
For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA.
sin angle = opposite side / hypotenuse
cosine angle = adjacent side / hypotenuse
tangent angle = opposite side / adjacent side
If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
cos (L) = j/k
So 1 USD is 2.89 RON
That means...
177 ÷ 2.89 = 61.24USD
