Answer:
x = 5 or x = -11
Step-by-step explanation:
(x+3)²+8=72
x² + 6x + 9 + 8 = 72
x² + 6x -55 = 0
(x - 5) (x + 11) = 0
x = 5 or x = -11
Answer:
m∠EAN =154°
Step-by-step 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)
