Answer:
b. 2692 ft
Step-by-step explanation:
The relation of interest between the sides of the right triangle is ...
Tan = Opposite/Adjacent
Using the given numbers, that is ...
tan(32°) = (building height)/(4300 ft)
Multiplying by 4300 ft, we get ...
building height = (4300 ft)·tan(32°) ≈ 2686.9 ft
This is the height above the observer's eyes, so the height of the building above the ground is ...
2687 +5 = 2692 . . . . feet
The building is 2692 feet tall.
can someone please help!!!!!!
Answer:
height of the Eiffel tower ≈ 300.0 m(nearest tenth of a meter)
Step-by-step explanation:
The triangle TDE is not a right angle triangle. Angle TDE can be gotten by subtracting 63° from 180°. Angle on a straight line is 180°. Therefore, 180° - 63° = 117
°.
angle TDE = 117°
angle DTE = 180° - 117° - 31° = 32°
DE = 346.4 m
Side TD can be find using sine law
346.4/sin 32° = TD/sin 31°
cross multiply
346.4 × 0.51503807491 = 0.52991926423TD
178.409189149 = 0.52991926423TD
divide both sides by 0.52991926423
TD = 178.409189149/0.52991926423
TD = 336.672397461
TD ≈ 336.67 m
The side TD becomes the hypotenuse of the new right angle triangle formed with the height of the Eiffel tower.
Using sin ratio
sin 63° = opposite/hypotenuse
sin 63° = h/336.67
cross multiply
h = 336.67 × 0.89100652418
h = 299.975166498
height of the Eiffel tower ≈ 300.0 m(nearest tenth of a meter)
Answer:
is it A?
Step-by-step explanation:
I think it's A because no one has answered!
Answer:
all the angles add up to 180 degrees
So 180÷6=30
(i got 6 cuz 1+2+3)
so 1=30
2=30*2=60
3=30*3=90
