Answer:
c = 96°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
c is an exterior angle, thus
c = 50° + 46° = 96°
1.Make y the subject
k = xy
k/x = xy/x
y = k/x
2.Substitute
y = 7/9
y = 0.777......
y = 0.8 (Answer)
To confirm
k = 9 × 0.8
k = 7.2
k = 7 (constant)
