Answer:
Law of cosines to find missing measures
c^2= a^2+ b^2 - 2ab*cos(C)
Used because it is a SAS triangle
Step-by-step explanation:
This is known as a side, angle, side, or SAS triangle. We can find the missing measures by using the Law of cosines
c^2= a^2+b^2-2ab*cos(C)
Answer:
x=-3
Step-by-step explanation:
x+9 = 3.2=6
x= 6-9=-3
Answer:
x <
Step-by-step explanation:
Given
- ax + 4b > 9 ( isolate the term in x by subtracting 4b from both sides )
- ax > 9 - 4b ( divide both sides by - a )
Remembering to reverse the inequality symbol when dividing by a negative quantity, thus
x <
ANSWER
{x|x < -2 or x > 8}
EXPLANATION
The given absolute inequality is
By the definition of absolute value,
Multiply through the second inequality by -1 and reverse the inequality sign
Simplify
Divide through by 2
