Answer:
Step-by-step explanation:
A right triangle has one angle of 90.
If you add up all the angles ;
19+12+16= 47
It equals 47 so this is not a right triangle.
If it it is less than 90, it is an acute angle.
Therefore this angle is an acute triangle.
<span>f(x) =-(x+9)(x-21)
Manipulating algebrically,
We get,
</span>f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6

Answer:
40 degrees
Step-by-step explanation:
using 180 minus 94 we can find the inner left angle of the triangle as 86 degrees and using 86 plus 54 we get 140. 180 minus 140 for the last angle F so 40 degrees
Answer:
A positive correlation is a relationship between two variables in which both variables move in the same direction. Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases.
