Answer:
(x+1) (x−6)
Step-by-step explanation:
Answer:
Not a right triangle. See below for my reasoning.
Step-by-step explanation:
If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side: 7^2 + 9^2 = 11^2 => 49 + 81 = 121 But this is false.
Answer:
23
Step-by-step explanation:
Because the angles of a triangle always add up to 180°, you can set up an equation like this.




Answer:
c-24
a-156
Step-by-step explanation:
a=180-24( angles on s straight line)=156
c= 24 opposite angles
Answer:
x=2/3
Step-by-step explanation:
8 (3x-4)= 4x-2
24x-32= 4x-2
20x=30
x=2/3
