This week, I learned how to solve a certain angle but with a little twist.

 

First step: Label all the things I know.

Second Step: I figure out the missing angles. The opposite is 5 because 11 is the whole measurement and if we took away 6 because that is the whole square, it would be 5 leftover which is the triangle’s opposite. Also, after finding that out I used Pythagoras because the hypotenuse is the only side which has no value.

Third Step: I used sin because that’s the one that I like to use the most. Also, you can us either 3 but you can only do that when 3 numbers are given for each sides just like the example.

Fourth Step: 40 degrees is only angle LK, I added 90 degrees because that’s angle KN as well and they are asking for angle LKN.

130 degrees is angle LKN.
