What part of a right angle is 27 degrees 30 degrees 48 degrees?

a) In order to calculate what part of the right angle makes up an angle of 27 °, we will compose the proportion:

90 – 1,

27 – P.

P = 27 * 1: 90;

P = 27: 90;

P = 27/90 = 3/10 parts – from a right angle, makes an angle of 27 °.

b) In order to calculate what part of the right angle makes up an angle of 30 °, we will compose the proportion:

90 – 1,

30 – V.

V = 30 * 1: 90;

V = 30: 90;

V = 30/90 = 1/3 parts – from a right angle, makes an angle of 30 °.

c) In order to calculate what part of the right angle makes up an angle of 48 °, we will compose the proportion:

90 – 1,

48 – T.

T = 48 * 1: 90;

T = 48: 90;

T = 48/90 = 8/15 parts – from a right angle, makes an angle of 48 °.

Answer: a) 3/10 parts; b) 1/3 parts; c) 8/15 parts.
