Answer:
-(-5) ± √13 5 ± √13
x = ----------------------- = ---------------
2(3) 6
Step-by-step explanation:
This is a quadratic equation, with coefficients 3, -5 and 1.
The discriminant, b² - 4ac, turns out to be (-5)² - 4(3)(1), or 25 - 12 = 13
Thus, the roots are:
-(-5) ± √13 5 ± √13
x = ----------------------- = ---------------
2(3) 6
Answer:
b.
m<1 = 80 degrees because of the alternate angles rule.
m<2 = 100 degrees because angles on a straight line equals 180 degrees.
c.
m<1=75 degrees because again of the alternate angle rule.
m<2= 60 because that angle is equal to diagonally upper angle (I'll call it Z) and that angle would equal 60 because 180-120=60
Step-by-step explanation:
You really didn't need to do such complex math. If you want me to explain it more in detail, please let me know.
