Determine whether angle-angle-angle (AAA) is a valid means for establishing triangle congruence. If it is a valid criterion, exp
1 answer:
The angle-angle-angle is not a valid means for establishing triangle congruence.
<h3>What is the angle-angle-angle?</h3>This means the AAA similarity theorem, and it used to prove or disprove the similarities of triangles
It cannot be used to establish triangle congruence.
This is so because, triangles that have equal corresponding angles may or may not have equal corresponding side lengths

Answer:
Identity property of multiplication
Step-by-step explanation:
From step 5:
Here, to solve for x so that the variable x stands alone, Alberto uses the identity property of multiplication, which justifies what he has in step 6.
Step 6:
According to the identity property of multiplication, any value you multiply by 1 gives you that same value.
Therefore, 1x = 1 × x = x.
The variable x multiplied by 1 will give you x.
Answer:
y = -0.2x + 8
Step-by-step explanation:
To write a linear function, calculate the rate of change of the gallon of water leaving the tank and the starting level.
The function will describe the number of gallons over time or (time, gallons).
This means the function has data points (1, 7.8) and (9, 6.2).
Use the rate of change or slope formula to calculate it.
This means that for the formula y = mx+b then m = -0.2.
This also means that after losing 0.2 gallons the first hour it was at 7.8. So the starting value is 8 gallons.
The equation is y = -0.2 x + 8.
