Answer:
D. is the answer
Step-by-step explanation:
the side lengths always have to be equal so 6+8 = 10 and 10 is equal to 10
that means it makes a right triangle
Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos X = 
= 
= 
, then
∠ X = 
( ) ≈ 44° ( to the nearest degree ) → A
Answer:
(x+12)(x-12)
Step-by-step explanation:
When:
a = b = 0 we have point (0,0).
a = 0 and b ≠ 0 vertical line segment from (0, -b) to (0, b)
a ≠ 0 and b = 0 horizontal line segment from (-a, 0) to (a, 0)
a ≠ 0 and b ≠ 0 a ≠ b ellipse
a ≠ 0 and b ≠ 0 a = b circle
The answer is actually 42. Not 20.
You replace each x with 3
5(3)+9(3)
That 3 right next to the five means you multiply not add.
15+27=42
