Define angle bisector.An angle bisector is defined as a ray, segment, or line that bisects a given angle into two equal angles. The word bisection or half means dividing one object into two equal or identical parts. In geometry, we usually divide triangles and angles by lines or lines that are considered bisectors.
A geometric bisector is a ray, line, or segment that divides a given angle into two equal parts. For example, the bisector of a 60 degree angle divides it into two 30 degree angles. In other words, split the angle into two smaller congruent angles.
For the given case,
Ray BD bisects ∠ABC into two equal angles ∠ABD and ∠DBC; which can be written as ∠ABD = ¹/₂ ∠ABC.

You are standing on a footbridge that is 12 feet above a lake. You look down and see a duck in the water. The duck is 7 feet away from the footbridge. What is the angle of elevation from the duck to you? Round your answer to the nearest tenth. PLEASE HELPPPPPP
Answer:
Angle of elevation from the duck is [tex]59.7^{o}[/tex]
Step-by-step explanation:
This description can be represented by the three sides of a triangle and the given angle. Let the angle required be represented by θ. Thus applying the appropriate trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
So that,
Tan θ = [tex]\frac{12}{7}[/tex]
= 1.7143
θ = [tex]Tan^{-1}[/tex] 1.7143
= 59.7438
θ = [tex]59.7^{o}[/tex]
The angle of elevation from the duck is determined as [tex]59.7^{o}[/tex].

what is the slope of this graph?
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope = [tex]\frac{4-2}{1-3}[/tex]
= (-1)
Therefore, slope of the line is (-1).
June uses 12 eggs to make cupcakes. She uses four eggs for each batch of cupcakes. Which expressions can be used to find the number of batches she makes?

What is the measure of ZACD?
A. 65
B.
40
C.
25
D.
50"
Answer:
C. 25°
Step-by-step explanation:
A useful relation for this geometry is "an exterior angle of a triangle is equal to the sum of the remote interior angles." The measure of arc BC is the same as the measure of central angle BDC, which is an exterior angle of triangle ACD.
__
Triangle ACD has sides AD and CD that are radii of the circle, so it is an isosceles triangle with angle A ≅ angle C. Exterior angle BDC is the sum of those congruent angles:
∠BDC = ∠CAD +∠ACD
50° = 2×∠ACD
25° = ∠ACD . . . . . . . . divide by 2
E. a distance of 5 multiply 10^5 cm in 2 multiply 10^-5 seconds
Answer:
The speed is 900,000,000 km/h
Step-by-step explanation:
The ratio of distance covered to time taken gives the speed of an object
[tex]Speed, \ v = \dfrac{Distance, \ d}{Time, \ t}[/tex]
Given that the distance covered, d = 5 × 10⁵ cm
The time to travel the given distance, t = 2 × 10⁻⁵ seconds
Therefore;
[tex]Speed, \ v = \dfrac{5 \times 10^{5} \ cm}{2 \times 10^{-5} \ s} = 2.5 \times 10 ^{10} \ cm/s[/tex]
In km/h, we have;
1 cm = 0.00001 km
∴ v = 2.5 × 10¹⁰ cm/s × 1 km/(100,000 cm) × 3,600 s/h = 900,000,000 km/h
The speed is 2.5 × 10¹⁰ cm/s or 900,000,000 km/h.
