Question

M∠1=57°, m∠4=85°, m∠6=12°. Find m∠EAN.

Answer 1

m∠EAN =154°

Explanation:

m∠EAN = m∠1 + m∠4 + m∠6

as given in figure we can see that m∠EAN constitute three angles angle 1, 4 and 6

hence m∠EAN will be sum of these three angles.

Given

m∠1=57°, m∠4=85°, m∠6=12°.

m∠EAN = 57° + 85° + 12° = 154° (answer)
