The point of observation is 2500 m away from the foot of the building.
The angle of elevation is 4°.
We need to find the height 'h' of the building.
With respect to 4°,
2500 is the adjacent side.
'h' is the opposite side.
The trigonometric ratio associating opposite & adjacent is tan.
We have


Cross multiplying we get
h = 2500 tan4°
h= 174.82 m
Option B) is the right answer.
China plate is 12 years (16-4) and Glass plate is 4 years (12÷3)
Answer:
The missing number is 1000
Step-by-step explanation:
0.037 × ? = 37
Divide both sides by 0.037.

Expand
by multiplying both the numerator and the denominator by 1000.

Divide 37000 by 37 to get 1000.

Answer:
x = 41
Step-by-step explanation:
We know these angles will be equal to each other (they are across from each other, I honestly forget the term ) so we can set up an equation
Our equation from given: 104 = 3x - 19
Adding 19 to both sides 123 = 3x
Dividing both sides by 3: 41 = x
Answer: x = 41
Lines b and c
they both go up 2 and over 1 (rise over run is slope)
