Those two angles are congruent(corresponding), so we can set these equal to each other.
19x+3=21x-3
-2x=-6
x=3

If an object is dropped from a tower, then the velocity, V (in feet per second), of the object after t seconds can be obtained b
Amiraneli [1.4K]

Answer:

259.6 ft/sec

Step-by-step explanation:

it is a universal standard that acceleration due to gravity is 32ft/sec^2.

Now it can be verified by equation,

V(f) = V(i)+at (1st equation of motion derived by Newton's three laws of motion)

where,

V(f) is final velocity

V(i) is initial velocity

a is acceleration which is constant and have value 32ft/sec^2

t is time which is given as 7.8 seconds

In the given case, initial velocity that is V(i) will be 0ft/sec. Because, on dropping, object will start to move under the influence of gravity from zero speed.

So,

V(f) = 0 +(32) (7.8)

V(f) = 249.6 ft/sec

Now the condition is given that you have to add a constant 10 to the answer.

so, V(f) = 249.6 + 10

      V(f) = 259.6 ft/sec

Write the conversion factor for converting meters to centimeters
posledela
Since we are converting meters to centimeters we are converting large to small.

Expect the answer to be a larger number.  Here are some example of large to small:
2 weeks (larger unit) = 14 days (smaller unit)   14 is larger than 2
4 days (larger unit )  = 96 hours (smaller unit)  96 is larger than 4
Since there are 100cm in a meter, when we change meters to cm, we need a bigger number.  The conversion factor is 100 and should be used as a multiplier.
Example:  47m x 100 = 4700 cm
