Given that / and /, which postulate or theorem can be used to show that all 3 center triangles in the Antigua and Barbuda flag are similar?

Answers

Answer 1

Answer: Given that we assume that all the bases of the triangles are parallel.

We can use AAA or Angle-Angle-Angle to prove that these triangles are similar.

Each parallel line creates the same angle when intersecting with the same side.
For example:
The bases of each triangle cross the left side of all the triangle.
Each angle made by the intersecting of the the parallel base and the side are the same.
Thus, each corresponding angle of all the triangles are congruent.
If these angles are congruent, then we have similar triangles.

rob owns 6 green t-shirts and 15 t-shirts in other colors. if rob randomly selects a t-shirt to wear, what is the probability it will be green?

Answers

The probability that Rob will randomly select a green t-shirt, given that he has 6 green and 15 of other colors, is 2/7.

Answer:

2/7

Step-by-step explanation:

P (probability) = number of successful events / number of all events

P = 6 / (6+15) = 6 / 21 = 2 / 7

36b^2 − 24b + 8
16x^2 + 24x + 9
4a^2 − 10a + 25

Answers

Answer:

16x^2 + 24x + 9

Step-by-step explanation:

perfect square trinomial is of the form

a^2 + 2 * a * b + b^2

9x^2 + 9x + 1 = (3x)^2 + 3*3x*1 + 1^2 not a perfect square trinomial

36b^2 − 24b + 8 = ( 6b)^2 -2 * 6b *2 + ( 2 sqrt(2)) ^2 not a perfect square trinomial

16x^2 + 24x + 9 = ( 4x) ^2 + 2 * ( 4x) * 3 + 3^2 = perfect square trinomial

4a^2 − 10a + 25 = ( 2a) ^2 - 1 * 2a *5 + 5^2 not a perfect square trinomial

Answer:

The third answer listed:

$16x^2+24x+9$

Step-by-step explanation:

The trinomial:

$16x^2+24x+9$

can be factored out as follows:

$16x^2+24x+9\n(4x)^2+24x+3^2\n(4x)^2+12x+12x+3^2\n4x(4x+3)+3(4x+3)\n(4x+3)\,(4x+3)\n(4x+3)^2$

which as can be seen,is the perfect square of a binomial, so this trinomial is what is called a perfect square trinomial.
