Anumber less 7 is greater than -45. how can the solutions for this inequality be described? is -40 a solution?

All numbers greater than -38.; no

Step-by-step explanation:

Any value of x that is greater than -38 will satisfy the inequality. However, -40 is not greater than -38.

I hope this helps :) :)

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
