Answer:
Step-by-step explanation:
Alright, lets get started.
When two secants intersects outside a circle then the measure of the angle formed is half of the positive difference of the measures of the intercepted arcs. (Please refer the diagram I have attached)
Hence the measure of ∠1 is :
∠1=[tex]\frac{1}{2}(100-30)[/tex]
∠1=[tex]\frac{1}{2}*70=35[/tex]
hence the answer is 35°. : Answer
