Question

Here P, Q and R are collinear points and TQ  PR.
Name :
(i) a pair of complementary angles
(ii) two pairs of supplementary angles.
(iii) four pairs of adjacent angles.

Answer 1

Answer:

Required AnsweR :

\begin{gathered}\\ \longrightarrow\sf{ \dfrac{30}{100}\times 50}\end{gathered}

⟶

100

30

×50

\begin{gathered}\\ \longrightarrow\sf{ \dfrac{1500}{100}}\end{gathered}

⟶

100

1500

\begin{gathered}\\ \longrightarrow\sf{ 15}\end{gathered}

⟶15

30% of 50 is 15 .

Answer 2

Answer:

) Complementary angles are those whose sum is 90°. ∴ ∠TQS and ∠SQR are pair of complementary angles, as their sum is 90°.

(b) Supplementary angles are those whose sum is 180°. ∴ ∠SQR, ∠SQP; ∠TQR, ∠TQP are pair so supplementary angles.

(c) Two angles are called adjacent angles, if they have a common vertex and a common arm but no common interior points

. ∴ ∠SQR, ∠SQT, ∠TQR, ∠TQP, ∠SQT, ∠TQP; ∠PQS, ∠SQR are pairs of adjacent angles.
