Answer:
The pairs of supplementary angles are
∠4 and ∠3 , ∠3 and ∠6 , ∠4 and ∠5 .
Step-by-step explanation:
Definition of supplementary angles
When sum of two angles are 180° they are called supplementary angles .
As figure given in the question
∠3 = 90°
Thus
∠3 + ∠6 = 180 °
(By using Linear pair property)
∠4 + ∠5 = 180 °
(By using Linear pair property)
∠3 + ∠4 = 180 °
(By using Linear pair property)
Therefore the pairs of supplementary angles are
∠4 and ∠3 , ∠3 and ∠6 , ∠4 and ∠5 .

Answer:
3p³ + 2p² – 3p – 11
Step-by-step explanation:
From the question given above, the following data were obtained:
Side 1 (S₁) = –1(p + 5)
Side 2 (S₂) = 2(p² – 3)
Side 3 (S₃) = 3p³ – 2p
Perimeter (P) =?
The perimeter of the triangle can be obtained as follow
P = S₁ + S₂ + S₃
P = –1(p + 5) + 2(p² – 3) + 3p³ – 2p
Clear bracket
P = –p – 5 + 2p² – 6 + 3p³ – 2p
Rearrange
P = 3p³ + 2p² – 2p – p – 6 – 5
P = 3p³ + 2p² – 3p – 11
Therefore, the perimeter of the triangle is 3p³ + 2p² – 3p – 11
