Answer:
Solution given:
In right angled triangle
ABC.
with respect to <C=40°
opposite side=AB
adjacent=BC=DE=30ft
now
relationship between opposite side and adjacent
is given by tan angle
tan 40°=oppo/adjacent
tan40°=AB/30
AB=tan40*30
AB=25.2
<u>Now</u><u> </u>
<u>height</u><u> </u><u>of</u><u> </u><u>flagpole</u><u> </u><u>=</u><u>AB</u><u>+</u><u>BE</u><u>=</u><u>2</u><u>5</u><u>.</u><u>2</u><u>+</u><u>5</u><u>=</u><u>3</u><u>0</u><u>.</u><u>2</u><u>f</u><u>t</u>

Step-by-step explanation:
6(x+4)=30
1) Distribute 6 to x and 4:
6x+24=30
2) Subtract 24 from both sides:
6x=6
3) Divide both sides by 6:
x=1
