Find the measure of the missing angles.
X=
Y=
Z=

X= 41

Y= 90

Z= 41

Step-by-step explanation:

X=Z

Y+49=139

Z+Y+49=180

X+139=180

139+49+X+Z+Y=180

These we know because of the placement of the angles.

Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.

X+139=180

X=41

X=Z.

49+Z+Y=180

49+41+Y=180

90+Y=180

Y=90

Thus,

X= 41

Y= 90

Z= 41

To check, let's add them all together.

41+90+41+139+49=

360

This is correct!

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345
