Arte-miy333 [17]

Answer:

Step-by-step explanation:

1) Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

2) The vertex of a parabola is the point at the top or bottom of the parabola.

3) 'h' is -6, the first coordinate in the vertex.

4) 'k' is -4, the second coordinate in the vertex.

5) 'x' is -2, the first coordinate in the other point.

Examine the diagram. A triangle has angles A, 15 degrees, 80 degrees. The exterior angle to angle A is B. What is the sum of the

QveST [7]

Answer:

m<A = 30degrees

m<B = 70degrees

Step-by-step explanation:

Find the diagram attached

From the diagram;

m<A + 150 = 180

m<A = 180 - 150

m<A = 30degrees

Also since the sum of angles in a triangle is 180degrees, hence;

m<B+m<A + 80 = 180

m<B+30+80 = 180

m<B+110 = 180

m<B = 180 - 110

m<B = 70degrees
