Find the measure of arc EB. Circle A is intersected by line CD at points D and E and line CB at point B, forming angle ECB outside of the circle, the measure of angle ECB is 25 degrees, arc EB is 4x plus 16 degrees, and arc DB 7x plus 6 degrees.

= 96°

Step-by-step explanation:

From the figure attached,

m∠ECB = 25°

degrees

degrees

From the theorem of secants intersecting outside the circle,

m∠ECB =

25° =

25° =

50 = 3x - 10

3x = 60

x =

x = 20

= (4 × 20 + 16)°

        = (80 + 16)°

        = 96°

Therefore, measure of arc EB is 96°.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
