Answer:6.5
Step-by-step explanation:
If the diameter of the circle is 13 and the radius is half of the diameter than divide 13 by 2 and get 6.5
Step-by-step explanation:
1. vertically opposite angles are the same
b = 42
360 - (42 + 42)
360 - 84 = 276
276 ÷ 2 = 138
c = 138
2. angles in a triangle sum to 180
right angles = 90
180 - (90 + 62)
180 - 152 = 28
angle S = 28
3. 1st question no, unless one angle is given a number. angles are the same vertically opposite so the other 2 angles are also vertically opposite but angle is different size but by adding the 2 different angles, make them supplementary as they sum to 180. 2nd question yes. you could have 4 right angles.
