1.) what is the measure of ∠k, to the nearest degree? a. ) 13° b.) 24° c.) 66° d.) 72° 2.) what is the measure of ∠r to the nearest degree? a.) 31° b.) 53° c.) 58° d.) 80°

We know that
the law of sines establish
a/sin A=b/sin B

problem N 1

50/sin K=53/sin 76> 50*sin 76=53*sin K> sin K=50*sin 76/53
sin K=0.9154
K=arc sin (0.9154)> K=66.25°> K=66°

the answer problem N 1 is the option
c.) 66°

Problem N 2

30/sin R=35/sin 69> sin R=30*sin 69/35> sin R=0.8002
R=arc sin(0.8002)> R=53.15°> R=53°

the answer problem N 2 is the option
b.) 53°
