Hope this helps :D
Answer:
r=3
Step-by-step explanation:
- The equation of a circumference is
. - Then , in this case
, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.
Based on corresponding angles, the upper left angle will be the supplement of 130, which is 50 degrees. The upper right angle is perpendicular, so it is 90 degrees. Since the sum of all internal angles of a triangle is 180, the remaining angle (lower angle) is 40 degrees. This is choice G.
Only the first one.
A is the answer.
ABC and DEF are similar, A is to D, B is to E, and C is to F. match the corresponding letters.
