Answer:

$the \: third \: angle \: of \: triangle \: is \: 70 \\sum \: of \: triangle \: angles = 180 \: \\ 70 + 5x + 6x - 11 = 180 \\ 11x + 59 = 180 \\ 11x = 180 - 59 = 121 \\ x = 121 \div 11 = 11$

Answer:

Identity property of multiplication

Step-by-step explanation:

From step 5:

$1x = 20$

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:

$x = 20$

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.
