(2 marks) Q-12-, Evaluate 297 × 303 by using identity. (2 marks) Q-13- The measures of two adjacent angles of a parallelogram are in the ratio 3:2. Find the measure of each of the angles of the parallelogram. (2 marks) Q-14- (a) What is the minimum interior angle possible for a regular polygon? Why.​

Answer 1

Step-by-step explanation:

hey friend I will only answer 2 q

so 1》let one no.=x

other no.=x+15

so ATQ

X+X+15=95

SO 2X+15=95

2X=95-15=80

X=

$\frac{80}{2} = 40$

1st no =40

other no.=40+15=55

2》Add: p(p – q), q(q – r) and r(r – p).

so

p(p-q)+q(q-r)+r(r-p)

=p²-pq + q²-qr + r²-rp
