DCB = 78°

Step-by-step explanation:

A straight line is 180° so the angles ACD and DCB must add up to 180° so: 4x+2+3x+3=180

From here it's normal algebra, add like terms so it will be 7x+5=180

subtract 5 from both sides so it will be 7x=175

Divide both sides by 7 so we will get X=25 but we aren't done yet! We need to substitute the value of X into the angle DCB so we can get the real value so:

3(25)+3=78

Hope I helped!

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
