K/6.6 + 44.1 = 21.4

The solution is k =

the interior angles of a triangle when added together will equal 180 degrees

which means 44.1 +47.6 +x = 180

can you find x?

 m∡K = 88.3° .

m∡K = 180 − (44.1 + 47.6)

         = 180 − 91.7 = 88.3 .

but which class are u may know that first

96 39 cause 135 -96=39 im smart (i used a calculater)
