Answer:
m∠2 = 16° or 25°
Step-by-step explanation:
The sum of angles 1 and 2 is congruent to angle CED.
20° +(x^2)° = (9x)°
x^2 -9x +20 = 0 . . . . . divide by °, put in standard form
(x -5)(x -4) = 0 . . . . . . . factor
x = 5 or 4
m∠2 = (x^2)° = (5^2)° or (4^2)°
m∠2 = 16° or 25°
Answer:
-(1/10)x
Step-by-step explanation:
This is an addition problem. Since the variable (x) is the same in both terms, we need only sum up the coefficients -3/5 and 1/2 and then multiply x by this sum.
-3/5x+1/2x = (-3/5 + 1/2)x
The LCD of -3/5 and 1/2 is 10. The -3/5 term converts to -6/10 and the 1/2 term to 5/10. Thus, we have (-6/10 + 5/10)x = -(1/10)x
