What is five-sixths of the sum of k and 7 minus the product of 6 and c<br><br> Its algebra

dedylja [7]

The sum of 'k' and '7' is ' k + 7 '.

Five-sixths of that sum is ' (5/6)(k + 7) '.

The product of '6' and 'c' is '6c' .

"Five sixths of the sum of 'k' and '7' " minus the of '6'and 'c' is

<em> (5/6)(k + 7) - 6c</em>.

Given: △KLM, LM=20 3

egoroff_w [7]

Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.

KM = 30 + 10√3

KL = 10√6
