So first, you want to open the parenthesis here.

So, to do that, first look at the symbol before the parenthesis.

In this case it's a -.

So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)

So,

9x - 2x - 8

Or simplified,

7x - 8

Use the figure to find the measures of the numbered angles. ∠5 = ∠6 =
Gwar [14]

Answer:

∠ 5 = 49°, ∠ 6 = 131°

Step-by-step explanation:

∠ 5 and 49° are corresponding angles and are congruent, then

∠ 5 = 49°

∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is

∠ 6 + ∠ 5 = 180°

∠ 6 + 49° = 180° ( subtract 49° from both sides )

∠ 6 = 131°
