We know that electromagnetic waves consist of electric and magnetic fields. What is the angle between these fields in E-M radiation?

Write your answer in degrees. So if you think that angle between these fields is $33.3^{\\circ}$ write \"33\" in the box below. Please round your answer to a single degree (don't add any fractional parts).
