Answer quick ! in the figure, angle d measures 71° and angle g measures 37°. what is the measurement of angle a?

  34°

Step-by-step explanation:

You know the following relationships are true:

Using the first two equations, you can write expressions for C and E, then substitute those into the last equation:

  C = 90 - A

  E = 90 - G

  (90 -A) + D + (90-G) = 180

  A = D - G . . . . . . . add A-180 to both sides

  A = 71° -37°

  A = 34°

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.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
