Answer:
Step-by-step explanation:
Easy the three angles of a triangle equal 180 degrees 
so 60+75 = 135 --> 180-135= 
1) 145
2) 35
3)  no since the tops a 100 and its a Isosceles triangle two corners left it be 40 for each corner 
4) 34 for both x's cause 34+34+112. = 180
5) 180- 120= 60- 10 = 50/4 is (12.5)= x
6) x = 15 cause it be 120- 60 to get 60
