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].

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.

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.

Which statements are true about the toolbox? Select two options.
The shape can be broken into a rectangular prism and a triangular prism.
The shape can be broken into a rectangular prism and a rectangular pyramid.
The formula for the volume of this figure is V = B h + one-third B h.
The volume of the toolbox is 840 inches cubed
The volume of the toolbox is 900 inches cubed
Answer:
Option A and E.
Step-by-step explanation:
It is mentioned that Chiyo has a toolbox having a rectangular prism shape with a length of 8 inches, width of 15 inches, and height of 6 inches.
In addition to this, A triangular prism with a triangular base with base 8 inches and height 3 inches. The prism has a height of 15 inches.
So here the shape can be broken into a triangular prism and rectangular prism
Therefore the first option is correct
Now as we know that
Volume of the rectangular prism is
= l×b× h
= 8 × 15 × 6
= 720
And, the volume of the triangular prism is bh
And, the area of the triangular prism is 1 ÷ 2 × b × h
= 1 ÷ 2 × 8 × 3
= 12
Now the volume is
= 12 × 15
= 180
So, the volume of the tool box is
= 720 + 180
= 900
Hence, the last option is correct
