Step-by-step explanation:
3)Given Question:-
Find p[V2) for the following polynomial plx) = x + 2x+ 6.
Correction:- P(x)=x^2+2x+6
Solution:-
Given Polynomial P(x)=x^2+2x+6
Now Substituting x = √2 in P(x) then
=> P(√2)=(√2)^2+2(√2)+6
=> P(√2) = 2+2√2+6
P(√2) = 8+2√2
Answer:-
The value of P(√2) for the given problem is 8+2√2
4) Given :-
The angles of quadrilateral are in the ratio 3:5:9:13.
To find:-
Find all the angles of the quadrilateral ?
Solution:-
The ratio of the angles of a quadrilateral = 3:5:9:13.
Let they be 3X° ; 5X° ; 9X° ; 13X°
We know that
The sum of all interior angles of a quadrilateral is 360°
=>3X° + 5X° + 9X° + 13X° = 360°
=>30X° = 360°
=> X° = 360°/30°
=> X°=12°
now,
3X°=3×12°=36°
5X°=5×12°=60°
9X°=9×12°=108°
13X°=13×12°=156°
Answer:-
The four angles of the given quadrilateral are 36°,60° ,108° and 156°
