It is 3/13 - 2/13*i
Without an equality sign it's not an equation but it can be simplified to: 7x-5
cotA*cotB*cotC = 1/[tanA+tanB+tanC]
It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.

76 plus 54 plus 92 plus 88 plus 76 plus 88 plus 75 plus 93 plus 92 plus 68 plus 88 plus 76 plus 76 plus 88 plus 80 plus 70 plus 88plus 72 equal 1,440
The answer is 672.
27x3+6=87.
