c)5
Answers
Step-by-step explanation:
Question 1:
Define the following terms:
(i) Angle
(ii) Interior of an angle
(iii) Obtuse angle
(iv) Reflex angle
(v) Complementary angles
(vi) Supplementary angles
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°.
Answer:
5=y (c)
Step-by-step explanation:
50-y = 40+y
Inter change the digits..
50-40=y+y
10=2y
10÷2=y
5=y
