A stone dropped from a bridge strikes the water 2.2 s later. How high is the bridge above thewater

1 answer:

7 0

Since you are giving no information whatsoever, the formula could be:

S = (1/2)g.t², where s is the distance, 9 =9.8 m/s² and t = time
S = (1/2).(9.8)(2.2)² ans S= 23.7 meters

Find the measure of angle x in the figure below A.35° B.47° C.51° D.62°

Dafna11 [192]

First of all, we know that a line is 180°. This means if we add the angles of 61°, 57°, and angle y, we should get 180°.

$\sf 61\textdegree +57\textdegree+y=180\textdegree$

Simplify:

$\sf 118\textdegree +y=180\textdegree$

Subtract 118° to both sides:

$\sf y=62\textdegree$

We also know that all three angles of a triangle add up to 180°. So we have:

$\sf 67\textdegree+62\textdegree +x=180\textdegree$

Simplify:

$\sf 129\textdegree +x=180\textdegree$

Subtract 129° to both sides:

$\sf x=\boxed{\sf 51\textdegree}$

All really need to do is pick one number. so, we will go with 6 and 87.

6 times 12 is 72 then you subtract that from $87.

That would be 15

To double check, you can use another one. 9 and 123.

9 times 12 is 108. subtract that from 123 and you get 15.

Your answer is B) $15

Hope I helped :)
