Answer:

The measure of angle DCF is 129 degrees.

Step-by-step explanation:

Angle DCF is the sum of angle DCE plus angle ECF.

This is because, DCF is the main angle and DCE and ECF are its two parts.

Hence, the measure of angle DCF will be = $75+54=129$ degrees.

The answer is :

The measure of angle DCF is 129 degrees.

Find the value of x

Paladinen [302]

$\qquad \qquad \bf \huge\star \: \: \large{ \underline{Answer} } \huge \: \: \star$

x = 12°

$\textsf{ \underline{\underline{Steps to solve the problem} }:}$

$\qquad❖ \: \sf \:2x + 6 + 5x + 90 = 180$

[ by linear pair ]

$\qquad❖ \: \sf \:7x + 6 = 180 - 90$

$\qquad❖ \: \sf \:7x + 6 = 90$

$\qquad❖ \: \sf \:7x = 90 - 6$

$\qquad❖ \: \sf \:7x = 84$

$\qquad❖ \: \sf \:x = 84 \div 7$

$\qquad❖ \: \sf \:x = 12$

$\qquad \large \sf {Conclusion} :$

$\qquad❖ \: \sf \:x = 12 \degree$

docker41 [41]

Step-by-step explanation:

(x²-1)(x+1)≥0

As it has two multiples,

Therefore,

Either,
