Answer:

∠BCD = 28°

Step-by-step explanation:

arc BD = 2 x inscribed angle ∠BFD = 2 x 76 = 152

arc BFE = 360 - arc BD = 360 - 152 = 208

tangent-tangent angle ∠BCD = (arc BFE - arc BD)/2 = (208 - 152)/2 = 28

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°

elena-s [515]

The percentage of students attend either public school or college will be 90%.

<h3>How to illustrate the percentage?</h3>

Let the students in public school be 40%

Let the students in college be 50%

Let those who stay at home be 10%

Therefore, the percentage of students attend either public school or college will be:

= 40% + 50%

= 90%

Therefore, the percentage of students attend either public school or college will be 90%.
