Step-by-step explanation:
WZ is tangent to the circle at point Z and YZ is radius.
(tangent radius theorem)
Since, side opposite to 90° angle is called hypotenuse.
So, x represents the length of hypotenuse of
Thus, by Pythagoras Theorem

Answer:
<em>m∠EBC = 34° </em>
Step-by-step explanation:
m∠DBC = m∠DBE + m∠ EBC
m∠DBC - m∠DBE = m∠EBC
(12x - 3)° - (5x + 12)° = (3x + 13)°
12x - 5x - 3 - 12 = 3x + 13
4x = 28
x = 7
<em>m∠EBC </em>= (3(7) + 13)° <em>= 34° </em>
