(x+(x+2)+(x+4)+(x+6))=4x+12=212

x+x+x+x(2+4+6)=4x+12=212

4x (2+4+6)=4x+12=212

4x(6+6)=4x+12=212

12+4x=4x+12=212

<u>-12            -12   -12</u>

4x=4x=200

<u>/4  /4  /4</u>

<u>x=x=50</u>

<u>x=50</u>

Which presents the value of c
Tems11 [23]

Answer:

It's choice 2.  c = 3 sin 45 / sin 40.

Step by-step explanation:

m< A = 180 - 45-95

= 180 - 140

= 40 degrees.

So by the Sine Rule:

c / sin 45 = 3 / sin A

Cross multiply:

c sin A = 3 sin 45

c =  3 sin 45 / sin 40.
