Answer 1

Explanation:

40 de grese

Answer 2

52°

Explanation:

The angle between two secants drawn from the point outside the circle is half the difference of the intercepted arcs.

`\sf \boxed{\bf \angle \ Y =(far \ arc - near \ arc)/(2)}`

`\sf \angle Y = \frac{m\overset{\frown}{GK} - m\overset{\frown}{CE}}{2}\\\\50 = \frac{152-m\overset{\frown}{CE}}{2}`

`50*2 = 152 - m\overset{\frown}{CE}\\\\100 = 152 - m\overset{\frown}{CE}`

`100 + m\overset{\frown}{CE} = 152\\\\`

`\sf m\overset{\frown}{CE}= 152 - 100\\\\m\overset{\frown}{CE} = 52^\circ`
