State whether or not the following triangles are similar. If not, explain why not. If so, write a similarity statement
valentinak56 [21]

9514 1404 393

Answer:

  a) ∆RLG ~ ∆NCP; SF: 3/2 (smaller to larger)

  b) no; different angles

Step-by-step explanation:

a) The triangles will be similar if their angles are congruent. The scale factor will be the ratio of any side to its corresponding side.

The third angle in ∆RLG is 180° -79° -67° = 34°. So, the two angles 34° and 67° in ∆RLG match the corresponding angles in ∆NCP. The triangles are similar by the AA postulate.

Working clockwise around each figure, the sequence of angles from lower left is 34°, 79°, 67°. So, we can write the similarity statement by naming the vertices in the same order: ∆RLG ~ ∆NCP.

The scale factor relating the second triangle to the first is ...

  NC/RL = 45/30 = 3/2

__

b) In order for the angles of one triangle to be congruent to the angles of the other triangle, at least one member of a list of two of the angles must match for the two triangles. Neither of the numbers 57°, 85° match either of the numbers 38°, 54°, so we know the two triangles have different angle measures. They cannot be similar.

Mathew mowed lawns for 3 hours and earned $6.20 per hour. Then he washed windows for 4 hours and earned $6.90 per hour. What wer
Shtirlitz [24]

Answer:

$6.60

Step-by-step explanation:

6.20 x 3 = 18.60

6.90 x 4 = 27.60

18.60 + 27.60 = 46.20

46.20 ÷ 7 = 6.60

Solve the inequality:<br>(x+2)/(x^2-3x)&gt;0​
makkiz [27]

Answer:

The inequality is equivalent to x(x+2)(x−3)>0 , with the additional conditions that x≠0 and x≠3 .

Since x(x+2)(x−3) only changes signs when crossing −2 , 0 and 3 , from the fact that the evaluating the polynomial at 4 yields 24 , we see that the polynomial is

positive over (3,∞)

negative over (0,3)

positive over (−2,0)

negative over (−∞,−2)

Thus the solution set for your inequality is (−2,0)∪(3,∞) .
