Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3
Answer:
is there any options for the answers
Step-by-step explanation:
The answer is A.
Angles 1 and 2 are congruent, therefore angle 2 = 122.
The sum of all three angles in a single triangle would be 180.
180 - 122 = 58
Therefore, each of the other angles have to be LESS than 58.
