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°
What you need to find is 80% of 750
There are many ways to figure that out but the way that I did it is to divide 750 by 100. The answer (7.5). Is 1% of 750
In all I had to do was multiply 7.5 x 80. Giving us the answer which is 600
10 and (-9)
ex. 10+-9=1
ex. 10(-9)= -90
-9 1/3 - (- 1 1/3) =
-9 1/3 + 1 1/3 =
-8 <==
