Answer:
18°
Step-by-step explanation:
A diameter cuts a circle into two arcs that are each 180°. An inscribed angle that intercepts an arc of 180° has a measure of 90°. Thus we have ...
... 5x = 90°
.. 90°/5 = x = 18°
Answer:
CANT ZOOM IN ITS SIDEWAYS CANT SEEEEE XD
Step-by-step explanation:
Let a =107° and b=42°;
So cos 107° cos 42° + sin 107° sin 42° = cosa.cos42 + sina.sinb = cos(a-b)
and cos 107° cos 42° + sin 107° sin 42° = cos(107-42) = cos(65°)
