Answer:
AD/AB = AB/AC
Step-by-step explanation:
If we take two triangules in that figure: ABC and ABD, both are triangles rectangles. We need to use the definition of cosine, with the angle in th A corner, we called ∅.
For the ABC triangle: cos(∅) = adjacent cathetus/hypotenuse = AD/AB
For the ABD triangle: cos(∅) = adjacent cathetus/hypotenuse = AB/AC
Then:
cos(∅) = AD/AB = AB/AC
Answer:
x = -10
y = -13
Step-by-step explanation:
-6(y + 3) + 4y = 8
-6y - 18 + 4y = 8
-2y - 18 = 8
+ 18 + 18
-2y (÷ -2) = 26 (÷ -2)
y = -13
x = -13 + 3
x = -10
Answer:
No, because 4 is repeated in the domain.
