Question

5) What is the value of n in the picture?

3n
n 14
A) 19
B) 33
C) 57
D) 41.5

Answer 1

that's super wrong .the answer cannot be 41.5 because if n=41.5 then 41.5 ×4 =166 +90 +14 =270 and that's wrong because in the diameter need have 180 not 270 so is 19×4+90+14=180 answer = 19

Answer 2

ok. because those two angles are sumplimentary, (they equal 180 degrees) we can set up an equations.
3n+n+14=180

then isolate the variable
4n+14=180
-14 -14
4n=166

then divide to undo the multiplication

4n=166
