Question

an angle whose measure five times of its complementary angle is given by option A 75 option B 15 option C 70 option D 25​

Answer 1

Answer:

x=75

Step-by-step explanation:

angle=x

complement=90-x

5(90-x)=x

450-5x=x-------> 450=6x

x=75

Answer 2

Answer:

(i) Two rays OA and OB, with a common end-point O, form an angle AOB that is represented as ∠AOB.

(ii) The interior of an angle is the set of all points in its plane, which lie on the same side of OA as B and also on the same side of OB as A.

(iii) An angle greater than 90° but less than 180° is called an obtuse angle.

(iv) An angle greater than 180° but less than 360° is called a reflex angle.

(v) Two angles are said to be complementary if the sum of their measures is 90°.

(vi) Two angles are said to be supplementary if the sum of their measures is 180°.
