Question

Q36. A linear equation that converts degree to grade is given by
9 D = G 10
(i) Draw the graph of the given linear equation by taking degree on x-axis and grade on y-axis.
(ii) If the degree measure is 81°, then what is the measurement in grade?
(iii) If the grade measure is 1109, then what is the measurement in degree? (iv) Is there a measurement which is numerically the same in both degree and grade? If yes, find it.

Answer 1

Answer:

2. Its supplement is (180-x).

x = 81+2(180=x)

x = 81+360–2x

3x = 441

x = 441/3 = 147.

The angle is 147 deg. Answer
