Step-by-step explanation:
<u>YELLOW TRIANGLE:</u>
<u>
</u>
<u>PURPLE TRIANGLE:</u>
Since one of the angle is 45°, x = BC = 6
To prove:

<u>PINK TRIANGLE:</u>
<u>
</u>
I am pretty sure it is 7985.5
The surface to be paint is 4 * 12*8.5= 408 ft squared
1 gallon.......75 ftsquared
x gallon.......408 ft squared
------------------------------------
x= 408/75= 5,44 gallons
Cross multiplication 13x -13 = 8x+12
combining like terms 13x -8x =12 +13
5x= 25 x= 5
x=5
Answer:
maybe 100000
