(I NEED HELP ASAP) plz

Given:

The two angles A and B are vertical angles.

The measure of ∠A is x and the measure of ∠B is 5x - 20.

We need to determine the measure of ∠A.

Value of x:

Since, the angles A and B are vertical angles and the vertical angles are always congruent.

Thus, we have;

Substituting the values, we have;

Adding both sides of the equation by 80, we have;

Thus, the value of x is 20.

Measure of ∠A:

The measure of ∠A can be determined by substituting x = 20 in the measure of angle A.

Thus, we get;

Thus, the measure of ∠A is 20°

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
