Answer:
Step-by-step explanation:
Remark
Triangle BAC is isosceles. It has 2 sides that are both radii of the circle. I assume that C is the center of the circle.
Givens
AC = BC Both of these are radii.
<BCD = 20o Given
<A and <B are equal Both are opposite a radii of the circle
C is the circle's center Assumed otherwise we can't do it.
Solution
<BCD is an exterior angle of Triangle ACB It's on the same straight line as D and A
The sum of 2 remote interior angles = the sum of the exterior angle.
BAC = ABC Stated above
BAC + ABC = 20 Stated right above.
2BAD = 20
BAD = 20/2
BAD = 10
Answer:
Step-by-step explanation:
so in the inverse property of addition, the sum will equal 0
mistake is in expression 3.
1/4 + 0.25.......should be 1/4 + (-0.25)
The answer is G bc the range is the y values and the graph shows the y values greater than one
Answer:
to the right of x = 2 the function is increasing
{ x | x > 2}
Step-by-step explanation:
Recall that this is a quadratic function, and therefore responds to the shape of a parabola. In this case is also a parabola with branches opening up since the coefficient of the square term is positive. So, we just need to find where the vertex is located, and we know that to the left of the x-value of the vertex the function is decreasing, and to the right of it the function is increasing.
The formula for the x of the vertex of a parabola of the form:
is
which in our case gives:
Therefore, to the left of x = 2 the function decreases , and to the right of x = 2 the function is increasing.
