Answer:

Length (Tallness) of tree = 27 m

Step-by-step explanation:

Pole length = 9 m

Pole shadow = 12 m

Pole Shadow : Length Ratio = 12 : 9 = 4 : 3

Tree shadow = 36 m

As per 'Shadow : Length' ratio = 4 : 3

36 : L = 4 : 3

Reciprocal, L : 36 = 3 : 4

L / 36 = 3 / 4

L = ( 36 x 3 ) / 4 = 108 / 4

Tree length = 27 m

Please help will give correct answer brainliest

kodGreya [7K]

Answer:

Step-by-step explanation:

Let us begin with the AA Similarity definition. It states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

This means that we need:

An angle of one triangle that is congruent to an angle of the other triangle.
Another angle of one triangle that is congruent to another angle of the other triangle.

For this problem, it is unclear that there are more than one angles that are congruent to each other. We see that angle <DEF and <ABC are congruent, but the problem does not give any other angles. In another case, we must find one more to prove similarity by the AA similarity theorem.

Identify the quadrant where each point is located. (-5,2) (5,-5) (2,-5) (-4,-5)

Tanzania [10]

(-5,2) is located in the II quadrant because the x is negative and the y is positive.

(5,-5) is located in the IV quadrant because the x is positive and the y is negative.

(2,-5) is also located in the IV quadrant because the x is positive and the y is negative.

(-4,-5) is located in the III quadrant because both x and y are negative.
