Please Help I Need To Answer This Quick!!.

A+B+C=180°( BY SUM OF ALL ANGLE IS 180°)

70°+40°+C=180°

110°+C=180°

C=180°-110°

C=70°

C+X=180°(BY LINEAR PAIR)

70°+X=180°

X=180°-110°

X=70°

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

so, converting firstly the mixed fractions to improper fractions and then "adding".
