Question

AOB is a straight line. If p : q = 4 : 5 , find the value of p ​

Answer 1

Answer:

let the ratio

be x

4x+5x= 180°( straight angle)

9x= 180°

x=180°÷9

x=20°

4x=4×20°

80°

5x=5×20°

100°

Answer 2

Answer:

$\huge \blue{\sf{ \underline{{♧given \ \: : }}}}$

$\blue♡ \bf p\ \: : \: q \: \: = \: 4 \ \: : \: 5$

$\huge \blue{\sf{ \underline{{♧to \: find\ \: : }}}}$

$\blue ♡\bf the \: value \: of \: p$

$\huge \blue{\sf{ \underline{{♧solution\ \: : }}}}$

$\blue♡ \bf the \: value \: of \: straight \\ \bf \: angle \: is \: 180 \degree \: . \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\blue♡ \bf let \: the \: ratio \: be \: (x)$

$\sf \to4x + 5x = 180 \degree$

$\sf \to9x = 180 \degree$

$\sf \to x = \frac{180}{9}$

$\sf \to x = 20 \degree$

$\blue♡ \bf the \: value \: of \: p \: is \: (4x).$

$\blue \to\sf 4 \times 20$

$\blue \to \sf80 \degree$

$\blue♡ \bf the \: value \: of \:q \: is \: (5x).$

$\blue \to\sf 5 \times 20$

$\blue \to \sf100 \degree$
