ab+bc+ca
{a}^{2} + ab + b ^{2}a2+ab+b2
uv / (u+v)
​

Answer 1

Answer:

(i) In circle C(O, r)

AB is the diameter.

So ∠APB = 90˚ (Angle in semi–circle)

(ii) Now in △APB

∠PAB = 180˚ – (∠APB + ∠ABP)

= 180˚ – (90˚ + 42˚)

= 180˚ – 132˚ = 48˚

∠PQB = ∠PAB = 48˚ (Angles of the same segment )

Hence

∠PQB = 48˚

Answer 2

Answer:

statement n += 4; is equivalent to:

a. ++n;

b. n = n + 4;

c. n + 1;

d. None

What will be the output of a and b in the following:

int a, b;

a = 10;

b = a++;

a. 10, 10

b. 10, 11

c. 11, 10

d. 11, 11

What will be the output of a++; when int a = -1;

a. 1

b. -1

c. 0

d. None

If int a = 25, b = 5, c = 0; What value is stored in
