In your notebook, draw a right angle and then draw a bisector of the right angle. label all parts. what are some properties of the angles formed by the bisector? use complete sentences for full credit.

Solution:   Construct a right angle triangle ABC right angled at B.

To construct angle bisector of right angle ,we need to draw arcs from A and C on both the sides with the use of protector.

then join both the intersections of arcs to make the bisector PQ which intersect AC at D.

Now as it is bisecting the right angle B ,therefore as ∠B = 90°

⇒ ∠ABD+∠DBC= 90°

⇒∠ABD+∠ABD= 90°

[ As angle bisector bisects the angle into two equal halves,∴∠A =∠DBC]

⇒2∠ABD= 90°

⇒∠ABD=45° =∠DBC

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
