Question

In figure 1 if y÷x -5 and 3÷x=4 then the value of x is ​

Answer 1

Answer:

$\frac{y}{x} = 5 \: and \: \: \: \frac{3}{x} = 4$

$y = 5x .....(i)\: \: and \: \: 3 = 4x.....(ii)$

$from \: (ii) \: \: x = \frac{3}{4}$

$putting \: the \: value \: of \: x \: in \: (i)$

$y = 5 \times \frac{3}{4}$

$y = \frac{15}{4}$

3.∠APQ+∠PRQ+∠y = 180* (∠s,in a straight line)

⇒ 50*+127* = 180*

⇒ ∠y+177* = 180*

⇒∠y = 180*- 177*

⇒ ∠y = 3*

interior angle ∠R = 180*-127* ∴ exterior ∠s,-180*

∠R = 53*

in∆PQR

∠x +3*+53*=180*

∠x=180*-56*

∠x = 24*
