Question

14. If & the у = 5 and NI = 4 then x = aa у xz​

Answer 1

Answer:

G={7,8} and H={5,4,2}

We know that the Cartesian product of P×Q of two non-empty sets P and Q is defined as

P×Q={(p,q):p∈P,q∈Q}

∴G×H={(7,5),(7,4),(7,2),(8,5),(8,4),(8,2)}

and H×G={(5,7),(5,8),(4,7),(4,8),(2,7),(2,8)}

Answer 2

Answer:

Step-by-step explanation:

Bring every variable in terms of "x"

y/x = 5

y = 5x

z/x = 4

z = 4x

Now according to the figure x + y + z = 180°

x + 5x + 4x = 180

10x = 180

x = 18°

So your required answer is B) 18°
