Find the volume of this triangular prism. 10 ft
12 ft
5 ft
16 ft
19.6 ft
I need the answer!!!

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

hello,

as   long as they add up to 180 its correct.
