Answer:

#64 = 18

#65 = 30

Step-by-step explanation:

Remember, the sum of all the angles in a triangle is equal to 180 degrees...

#64

123+ 39 = 162

180-162 = 18

#65

75 + 75 = 150

180-150 = 30

Answer:

18 and 30 degrees

Step-by-step explanation:

< a + <b + <c = 180 degrees

< b = 180 - (123+39) = 18 degrees

<b = 180 - 2(75) = 30 degrees
