Answer:
Step-by-step explanation:
A) If AB is a diameter, Then ACB is a 90 degrees angle because In a semi-circle (AB is a diameter which divides the circle into 2 equal parts), the angle opposite to the diameter is of 90 degrees.
So, <ACB = 90 degrees
Then <a = 180-90-28
=> <a = 62 degrees
B) The opposite interior angles of a quadrilateral inscribed in a circle add up to 180 degrees.
So,
=> <a + <b = 180
=> <b = 180-62
=> <b = 118 degrees
Answer:
Step-by-step explanation:
We first let 0.38 (8 being repeated) be T.
Since z is recurring in 1 decimal places, we multiply it by 10. 10z = 3.88
Next, we subtract them. 10 r T 3.88 0.38 9x 3.5
Lastly, we divide both sides by 9 to get IC as a fraction. 3.5 T 9 35 90 7 18
