WORK OUT ANGLE BXC.
GIVE A REASON FOR EACH ANGLE YOUR WORK OUT

a) Angle XBC = 55° because it is a corresponding angle to 55°

b) angle BXC = 70°

Step-by-step explanation:

ΔXBC is an isosceles triangle because XB = XC

∠XCB = ∠XBC because ΔXBC is an isosceles triangle

∠BXC = 180° - 55° - 55° = 70° because the sum of all the interior angles of a triangle - 180°

Step-by-step explanation:

a)

Angle XBC = 55° as XY and BD are parallel lines, the interior angles on the same side of a transversal are supplementary hence the same.

b)

Triangle BXC is isosceles when XBC and XCB are both 55°

XBC+XCB+BXC= 180° (sum of angles of triangle)

55°+55°+BXC=180°

110°+BXC= 180°

BXC= 180°-110°

BXC= 70°

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
