Answer:

Option D is correct.

No, the triangles are not similar.

Step-by-step explanation:

AA postulates states that two triangles are similar if they have two corresponding angles equal.

Labelled the diagram as shown below:

We know that sum of all the measure of the angles in a triangle is 180 degree.

In triangle  ABC:

\angle A + \angle B + \angle C = 180^{\circ}

⇒30.4^{\circ}+84.6^{\circ}+\angle C = 180^{\circ}

⇒115^{\circ}+\angle C = 180^{\circ}

Subtract 115 degree from both sides we get;

⇒\angle C = 65^{\circ}

In triangle ABC and PQR

\angle A = \angle Q = 84.6^{\circ}

\angle C \neq \angle R

i.e 65^{\circ}\neq 66^{\circ}

⇒These triangles does not satisfy the AA postulates

Therefore, the given triangles are not similar.

No, because 30.4+84.6+66=181
the sum of a triangle=180
so they are not similar.

Answer:

Plan C

Step-by-step explanation:

Complete the table first:

To find the number of weeks for each amount of $ to save, divide $500 by the amount.

Plan B: $500/$30 = 16.7 weeks, rounded to 17 weeks

Plan C: $500/$40 = 12.5 weeks, rounded to 13 weeks

Plan D: $500/$50 = 10 weeks

Save $500 in less than 16 weeks with $20 extra:

Which plans need less than 16 weeks?

Plans C and D.

Check the amount of money Plan C gives:

In 13 weeks, how much extra money does this plan give?

Extra money = Total - $500

The total money is 13 weeks * $40 = $520

$520 - $500 = $20 in extra money

Therefore Plan C gives Todd $500 in less than 16 weeks, with $20 extra.

MArishka [77]

Answer:

21.6 feet

Step-by-step explanation:

Assuming the desk is a rectangular shape, you would find the perimeter of his desk.

x = 2(6.5 + 4.3)

OR

6.5 + 6.5 + 4.3 + 4.3

=21.6

Hope this helped! :)
