I duno what the answer is but use the calculater

Let's evaluate ~
The given expression is :

plug the value of x as 3



Therefore, the required value is 20
6 + 4 + 4 = 14 cm
2 * pi * r =
2 * 3.14 * 3 = 18.84 / 2 = 9.42
14 + 9.42 = 23.42
Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>135</u></em><em><u>°</u></em></h2>
Step-by-step explanation:
<em><u>According</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>problem</u></em><em><u>, </u></em>
45° + x = 180° <em>[</em><em>Linear</em><em> </em><em>pair</em><em>]</em>
=> x = 180° - 45°
=> <em><u>x = 135° (Ans)</u></em>
That would be D
the first 3 = -12x + 24
bur D = -12x - 24
