Answer:
Is 3(b+c) equivalent expressions?
A. True
Answer:
4th one
Step-by-step explanation:
Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The
and
.
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.




The measure inscribed angle is half of the corresponding subtended arc.



AB is the tangent. So,
because radius is perpendicular on the tangent and the point of tangency.




Therefore,
and
.
The answer is a.) -27
subtract 11 from 38
27 keeps the negative sign because -38 is larger than 11
