Answer:
≈ 47.2 m
Step-by-step explanation:
let the height from the sea to the base of lighthouse be h₁
let the height from the sea to the top of the lighthouse be h₂
using the tangent ratio in the right triangle
tan55.1° = 
= 
( multiply both sides by 610 )
h₁ = 610 tan55.1°
tan56.5° = 
( multiply both sides by 610 )
h₂ = 610 tan56.5°
then
height of lighthouse = h₂ - h₁
= 610 tan56.5° - 610 tan55.1°
= 610(tan56.5° - tan55.1° )
≈ 47.2 m ( to the nearest tenth )
Answer:
1/5 gallon per minute
Step-by-step explanation:
The fill rate for container 1 is 2 gallons in 10 minutes. For container 2 it is 4 gallons in 10 minutes. The difference in rates is ...
(4 gal - 2 gal)/(10 min) = 2/10 gal/min = 1/5 gal/min
Answer:
Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
----> equation a
----> equation b
----> equation c
Solve the system by substitution
Substitute equation b and equation c in equation a
Solve for A
Find the measure of angle B
Find the measure of angle C
Answer:
See below ~
Step-by-step explanation:
<u>Finding x</u>
- 2x - 28 = x/2
- 3/2x = 28
- 3x = 56
- x = 56/3 = 18.66666667
- The exact side length of the small square is <u>18.66666667 cm</u> and the exact side length of the big square is <u>37.3333334 cm</u>.
- The approximate side length of the small square is <u>18.7 cm</u> and the approximate side length of the big square is <u>37.3 cm</u>.
