Find the measure of the angle indicated with a?, and enter the number only

9514 1404 393

  45°

Step-by-step explanation:

Arc YZ is the difference between the given arcs and 360°:

  126° +144° +YZ = 360°

  YZ = 360° -270° = 90°

The inscribed angle (?) is half the measure of the arc it intercepts:

  ? = 90°/2

  ? = 45°

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
