Four as zeros don't count when you're figuring out significant figures
Answer:
Step-by-step explanation:
The submersible is diving at a down angle of 15° along the hypotenuse AC of triangle ABC.
Its horizontal track along the surface AB is 1500 ft.
The submersible was already at a depth of 250 feet when it began the dive.
New depth = 250 + 402 = 652 ft
Using the slope concept, it is found that the thundercloud is 6.43 miles above the ground.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem, we have that:
- The vertical distance is the height h.
- The horizontal distance is of 3 miles, as the sound takes 5 seconds to travel 1 mile, and it took 15 seconds.
Hence:
tan(65º) = h/3.
h = 3 x tan(65º)
h = 6.43 miles.
The thundercloud is 6.43 miles above the ground.

Answer:
x=5.75
Step-by-step explanation:
As you can see, EH and FG are congruent, which means that the measurements must be the same.
You have 4x+5=28
That's already an equation! Now you solve it:
4x+5=28
4x=28-5
4x=23
x=5.75
