Question

If (3x+18)° and (2x-8)= are supplementary Angeles than find x.​

Answer 1

Answer:

27.4° or 27° 24’

Explanation:

Since 3x + 18° and 2x + 25° are supplementary angles  

∴ 3x + 18° + 2x + 25° = 180°  

⇒ 5x + 43° = 180°  

⇒ 5x =180° - 43° = 137°  

⇒ x = 137/5 = 27.4° or 27° 24’

If (3x+18)° and (2x-8) are equal to supplementary angeles than find x.

$\huge\mathcal{\fcolorbox{aqua}{azure}{\blue{❖Answer}}}$

$(3x \: + 18) + (2x - 8) = 180 \\ 3x + 2x \: + 18 - 8 = 180 \\ 5x + 10 = 180 \\ 5x = 180 - 10 \\ 5x \: = 170 \\ x = \frac{170}{5} \\ x = 34$

.°. Value of x = 34°
