It's 18 it means 18 times 3 becomes 54 and that's how you get it
Let's rewrite the mathematical expressions:
3 1/6 = 3.166666667
1 5/6 = 1.833333333
Subtracting both expressions we have:
3.166666667- 1.833333333 = 1.727272727
Answer:
Sean's ribbon is 1.727272727 in long than Fran's
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°
