Answer:
The camera had to cover the greatest angle is CAMERA 3 because it had the largest angle of 71.47°
Step-by-step explanation:
From the above question,
We have:
Camera 1 = Angle A
Camera 2= Angle B
Camera 3 = Angle C
A = 210ft
B = 234ft
C = 260ft
We need to find Angle A( angle of camera 1) using the cosine rule
A=(B² + C² - 2BCCosA)
210² = 234² + 260² - 2 × 234 × 260 × CosA
210² = 122356 - 121680CosA
Square both sides
210² = 122356 - 121680CosA
44100 = 122356 - 121680CosA
121680CosA = 122356 - 44100
121680CosA = 78256
Cos A = 78256/121680
Cos A = 0.6431295201
A = arc cos (0.6431295201)
A = 49.974422249°
Angle A approximately = 49.97°
Using the Sine rule to find the Angle B
A/Sine A = B/Sine B
210ft/Sine 49.97° = 234ft/Sine B
210ft × Sine B = 49.97° × 234ft
Sine B =( Sine 49.97° × 234ft)/210ft
B = arc sin (0.8532172354)
Angle B = 58.56334
Approximately = 58.56°
Angle C = 180 - (49.97 + 58.56)°
Angle C = 71.47°
Therefore, the camera had to cover the greatest angle is Camera 3 because it had the largest angle of 71.47°
Ending answer is -x^2+15x-48/x^2+16 but i'm bad at explaining, sorry. Hope it helped anyway!
- Another name for plane W is plane ABC.
- The intersection of plane ADE and plane W is line AD.
<h3>What is a plane?</h3>
A plane is also referred to as a two-dimensional surface and it can be defined as a flat, two-dimensional surface with zero curvature and zero thickness, that extends indefinitely (infinitely). Also, two (2) planes intersect at a line.
<h3>What are collinear points?</h3>
Collinear points can be defined as three or more points that all lie on the same straight line (single line). Based on the geometric figures shown in the image above, the three collinear points include the following:
<h3>How to name a plane?</h3>
A plane should be named by using any three (3) non-collinear points that are located on the plane while making use of an uppercase script letter.
Based on the geometric figure shown in the image attached above, another name for plane W is plane ABC. Also, the intersection of plane ADE and plane W is line AD.
