Every line from the tangent to the centre is 90°. This is said in the circle theorems.
So angle OBC and ODC are 90°.
angle O is twice the size of angle F. This is another circle theorem.
Therefore angle O is 152°.
The quadrilateral of ODBC would equal to 360°. Which means 90° + 90° + 152° = 332°
360° - 332° = 28°.
The answer is 28°
He will need 75ft. of sod. Just add up all of the ft. Measurements.
The answer is (6,9) because of the slope given . you put it in stat edit. i just made this up so i can complete the first steps of signing up.
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180°. So from the figure, we can see that

Collecting all similar terms, we get

or

So the angle measures are now as follows:
