Lines b and c are parallel. what is the measure of angle 6?

∠6 = 54°

Step-by-step explanation:

Since b and c are parallel lines, then

∠8 = 13x + 9 ( alternate exterior angle ) and

∠6 = 5x + 9 ( vertical angles )

∠6 and ∠8 form a straight angle and are supplementary, thus

13x + 9 + 5x + 9 = 180, that is

18x + 18 = 180 ( subtract 18 from both sides )

18x = 162 ( divide both sides by 18 )

x = 9

Hence

∠6 = 5x + 9 = (5 × 9) + 9 = 45 + 9 = 54°

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

all it means is function 3
