Make k the subject of the formula h(k+6)=3h-k

k = -

Step-by-step explanation:

Given

h(k + 6) = 3h - k ← distribute parenthesis on left side

hk + 6h = 3h - k ( add k to both sides )

hk + k + 6h = 3h ( subtract 6h from both sides )

hk + k = - 3h ← factor out k from each term on the left side

k(h + 1) = - 3h ( divide both sides by (h + 1) )

k = -

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
