XB−→− is the angle bisector of ∠AXC. m∠AXB=23°

∠AXC = 46°

∠BXC = 23°

Step-by-step explanation:

If XB is the angle bisector of ∠AXC then XB bisects ∠AXC t at X. Hence;

∠AXC = ∠AXB+∠BXC and ∠AXB=  ∠BXC

The equation becomes

∠AXC = ∠AXB+∠AXB

∠AXC = 2∠AXB

Given

m∠AXB=23°

Substitute the given angle into the expression above to get ∠AXC since we are not told what to find but we can as well find ∠AXC

∠AXC =2(23)

∠AXC = 46°

Also note that since ∠AXB=  ∠BXC, then ∠BXC will be 23°

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
