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

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)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: the equation matches the regression
