Question

I need some help on this one! Thanks!

Answer 1

1.

a. BCA = 30 degrees.

b. BCD = 90 degrees.

c. Because D is in a corner that is equivalent to a right angle or 90 degree angle.

2.

a. LOK = 37 degrees.

b. LOM = 180 degrees.

c. It is obtuse because the angle is greater that 90 degrees and the protractor does not need to be moves. BTW the angle is 143 degrees.
