First - Since you have a in the numerator and denominator, you can cancel them and get:
8r/12
Second - Since both 8 and 12 have common factors, you can find the GCF and divide both by that number.
GCF = 4
8/4=2
12/4=3

Answer:
38°
Step-by-step explanation:
All triangles have a sum of 180°
180 - (119 + 23) = missing angle
180 - (142) = missing angle
38 = missing angle
So, the missing angle has a measurement of 38°
3pie+12mm is the correct answer (A)
