the distance to the nearest foot from the base to the top of the tower is 184 feet .
<u>Step-by-step explanation:</u>
Here we have , The leaning tower of Pisa in Italy leans at an angle of about 84°. The figure below shows 52.1 meters from the base of the tower, the angle of elevation to the top is 50°. We need to find the distance to the nearest foot from the base to the top of the tower . Let's find out:
Let angle A = 50
Let Angle B = 84
Since the angles of a triangle must add up to 180, then
Angle C = 180-50-84 = 46
Now, use the law of sines to find the distance from the base to the top of the tower. That is the side of the triangle opposite Angle A. The distance of 52.1 feet is the side opposite Angle C. So:
⇒
⇒
⇒
⇒
⇒
Therefore , the distance (b) from the base to the top of the tower is 55 feet .
Answer:
9x
Step-by-step explanation:
because they're like terms add them together
3x + 6x = 3 + 6 =
9x, could i have brainliest if possible thanks!
Answer:
383.4 km
Step-by-step explanation:
The interior angle at the first turning point in the triangular flight path has measure 270° -215° = 55°. The law of cosines can be used to find the length of the final leg:
c² = a² +b² -2ab·cos(C)
c = √(125² +137² -2·125·137·cos(55°)) ≈ √14749.01 ≈ 121.4
The total length of the journey is then ...
round trip = 125 +137 +121.4 = 383.4 . . . km
___
In the attachment, the number at the bottom is the sum of the lengths of the two adjacent sides. The total length is then 125 +258.4 = 383.4 km.
