B- Observation
C- Experiment
D- Survey
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x

Answer:
The measurement of x is 56 degrees.
Step-by-step explanation:
Below that angle is a straight line measuring 180 degrees, so if one part of that 180 is 124 you would take 124 from 180.
180-124=x
x=56
Hope this has helped have a great day.
