Question

plaese solve as many answers as you can from the above pic ​

Answer 1

Step-by-step explanation:

2=》123+Triangle's 3rd angle=180 ( straight line)

triangle's 3rd angle= 180-123

triangle's 3rd angle = 57

so=》

47+57+y=180 (triangle's 3 angle plus is 180)

104+y=180

y= 180-140

y= 40

12=》 60+70+3rd angle = 180

130+3rd angle = 180

3rd angle =180 -130

3rd angle = 50

so

=》 50 +x= 180

x= 180 -50

x = 30

sorry I can solve only that questions but I am sure these answer will definitely correct. so plz mark me as a brainlist and plz see my bio plz

Answer 2
