Answer:
X=135 degrees
Step-by-step explanation:
the total interior angle of a triangle is 180.
To work this out you would first add the interior angles of B which is 69 and the interior angle of C which is 66, which gives you 135.
The next step is to minus 135 from 180, which gives you 45. This is because the total interior angle of a triangle is 180.
Then to work out the angle of x you would minus 45 from `180, which gives you 135. This is because the total angle in a straight line is 180 degrees.
1) Add the angles of 69 and 66.
2) Minus 135 from 180.
3) Minus 180 from 45.

Answer:
The coin was thrown from 448 feet
Time to hit the ground is 7 seconds
Step-by-step explanation:
Given
Solving (a): Height when coin is thrown
At this point t = 0
So, we have:
Solve expressions in the brackets
<em>Hence, the coin was thrown from 448 feet</em>
Solving (b): Time to hit the ground
At this point, h = 0.
So, we have:
Reorder
Divide both sides by -16
This gives:
or
or
Since, time can't be negative;
