Answer:
LA n LB = 25°
Step-by-step explanation:
1. 130°+0=180
=> 0=180-130
=> O= 50°
In triangle AOB (join LA to LB, imaginary line)
LA+LB+LC= 180°
LA+LB+50=180
LA+LB=180-50
LA+LA=130
2LA= 130
LA=130/2
LA=65
Therefore LA=LB=65(inner angle)
LA+LA( inner and outer angles)=90°
65 +LA=90
LA=90-65
LA= 25°
similarly,
LB+LB=90
65°+LB=90
LB=90-65
LB=25
