Answer:
799 feet
Step-by-step explanation:
We solve using the Trigonometric function of Tangent.
tan theta = Opposite /Adjacent
From the above question, we have the height of the surveyor = 5.5 feet
theta = Angle of elevation = 65°
Adjacent = 370 feet
Let Opposite = height + height of spider rock
tan 65° = h - 5.5 /370 feet
Cross Multiply
tan 65° × 370 feet = h - 5.5
793.46756059 feet = h - 5.5
h = 793.46756059 feet + 5.5
h = 798.96756059 feet
Approximately = 799 feet
The height of the Spider rock = 799 feet
Step-by-step explanation:
(3x-15)°= 105°
3x=120
x=40°
(y+25)°=180-105
(y+25)°=75°
y=75-25
y=50°
A. 6 and 10 because 6x10=60 and that’s the only one that does not equal 30.
2 (b+4)
2 being the factored coefficient
You have to mulitiply 6 times 8 which equals 48 and thats your answer.
