Askydiver jumps out of an airplane. emtiaz says that the skydiver should fall about 187.5 feet in 1.5 second. is his answer reasonable?

Answer:

No, his answer is not reasonable.

Explanation:

Given:

Sky diver jumps out of the airplane  

So the initial velocity of the diver (u) =0

Distance(s) travelled by him = 187.5 feet = 187.5×12/100=22.5 m

Time taken=1.5 seconds

Solution:

Using the formula

Where s= distance travelled  

t= time taken  

g= acceleration due to gravity

So according to question  

t=2.1428 sec

But Emtiaz says that the sky diver should take 1.5 sec to fall 187.5 feet

But the actual time taken is 2.1428 seconds,we can say that he is wrong.  

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
