James has a contract of paint 30 identical water tanks .he has to paint the outside surfaces of each tanks but not the top. Jane's knows that 1tin of paint is enough to cover 12^2 of surfaces costs $26.99 work out the total costs of the tin of the paints he will need for all 3p water tanks .

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

addition
