Answer:
First, you have to set 5x equal to (3x+10). They are vertical angles and therefore congruent.
5x = 3x+10 The variable should only be on one side of the equation,
5x - 3x = 10 Therefore subtract 3x from both sides
2x = 10 Divide by 2 on both sides.
x = 5
We're not done yet, since we've found the x-value we have to solve for ∠GEC.
∠GEC = 3x+10 = 3(5)+10 = 15+10 = 25°
∠GEC and ∠FEG form a right angle. This means that the sum of the two angles is 90°
90° = 25° + x In this case, we're using "x" to solve for ∠FEG
90-25 = x We subtract 25 from both sides to get the variable by itself.
65° = x
∠FEG = 65° The Answer is B
Step-by-step explanation:
D because a trapezoid has four sides and the top and bottom are parallel
The answer can be found by subtract the volume of the small box from the volume of big box.
Volume of the small box:
12*8*4= 384 inches cube
Volume of the big box:
20*15*9= 2700 inches cube
The space left:
2700 - 384 = 2316 inches cube
There are 4 hundredths or 4/100
820
bc it is not 825 or higher it stays the same
