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°
Answer: lol yes 5 units are the correct asnwser
you just have to count the blocks
Step-by-step explanation:
I hope you get a good grade on your i-ready test but dont cheat the hole way cuz you have to figure some of these out your self :) i did this once but i was litterly stup.id the next year have a nice day
A. is the answer. a2 + b2 = c2 is the formula used to find the hypotenuse (the longest leg)
Split it up into compound shapes, calculate the areas individually and then add and subtract the relevant quantities.
For instance, the shape in part a can be split up into a quarter circle, a trapezium and a half circle. I have included a diagram that may be of assistance in understanding what I mean but I leave the calculations to you. (They're quite easy when you split the shape up anyway)
