Question

q.no 2 and 3 plzz bhai log correct answer

Answer 1

hey
1.use the angle sum properties of triangle
30+90+19x+3=180
x=3
2.use the angle sum property
7x-4+6x-4+5x+8=180
x=10

hope iT helped

Answer 2

i)30+19x+3+90=19x+123÷180(angle sum)
19x=180-123=57
x=57/19=3
19x+3=60 degree

ii) (7x-4)+(6x-4)+(5x+8)=180
18x=180.
x=180/18=10
7x-4=7*10-4=66
6x-4=6*10-4=56.
5x+8=5*10+8=58

hope it helps. pls mark as brainliest... pls
