Answer:
90 degrees
Step-by-step explanation:
Angle BGD is supplementary with angle DGE.
BGD + DGE = 180
Since angle DGE is a right angle, then Angle BGD must also be a right angle:
BGD + 90 = 180
BGD = 90
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:

Recall that the vertex is given by the formulas:

In this case, <em>a</em> = -1, <em>b</em> = 2, and <em>c</em> = 1.
Determine the <em>x-</em>coordinate of the vertex:

To determine the <em>y-</em>coordinate, evaluate the function at <em>x</em> = 1:

In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.
Answer:
the answer is D {-5, -13}
14.7x + 4x = 0*(49y+39y) y = 14
18.7x = 0(686 + 546)
18.7x = 0
x = 0
We are given with
arc AC = 130
The measure of the arc on the other side of the circle is
360 - 130 = 230
Therefore, according to the theorem on circles, the measure of angle ABC is
(1/2) ( 230 - 130) = 50
