Answer:

Step-by-step explanation:

∠A=∠B               (V.O.A, Vertically oppt angles are eql)

5x-2=3x+12

5x-3x=12+2

2x=14

∴x=14÷2

x=7°

The perimeters of similar triangles are in the same ratio as the corresponding sides
wariber [46]

Answer:

Always

Step-by-step explanation:

Suppose you have triangle ABC with side lengths a, b, c. Suppose that is similar to triangle DEF with side lengths d, e, f.

Now, let k be the ratio of corresponding sides ...

  k = d/a

Because the same factor applies to all sides, we also have ...

  k = e/b = f/c

That is, if we multiply by the denominators of each of these fractions, we get ...

  • d = a·k
  • e =b·k
  • f = c·k

The perimeter of ΔABC is ...

   perimeter(ABC) = a + b + c

The perimeter of ΔDEF is ...

  perimeter(DEF) = d + e + f = a·k + b·k + c·k

  perimeter(DEF) = k(a + b + c) = k·perimeter(ABC)

  k = perimeter(DEF)/perimeter(ABC)

That is, the perimeters are in the same ratio as corresponding sides.

Your friend draws the diagram at the right
polet [3.4K]

Answer:

What he did wrong is that he did not flip all of the points. since S is 1 point up, it would then reflect 1 point down. point P is 3 up and the reflection should be 3 down. Q should be 3 down as well and R is 1 down below the x axis. The Y does not move for all of the points.

Step-by-step explanation:

I hope this helps!

145 is what percent of 620
Oksanka [162]

Hello There!

145 is 23.39% of 620

<u><em>HOW TO SOLVE</em></u>

<u><em></em></u>

<u><em>Equation: Y = P% * X</em></u>

<u><em>We need to solve our equation for "P"</em></u>

<u><em>P% = Y/X</em></u>

<u><em>P% = 145/620</em></u>

<u><em>p = 0.2339</em></u>

<u><em></em></u>

<u><em></em></u>

<u><em>Convert decimal to percent:</em></u>

<u><em>Percent = 0.2339 * 100 = 23.39%</em></u>

P(A)=0.40 p(b)= 0.50 p(A and b) = 0.10 what is p(b/A)? <br><br><br>plz help​
yawa3891 [41]

Answer:

The answer is C, 0.25.

Step-by-step explanation:

In order to find the probability of (B | A), you need to use this formula:

Conditional Probability (A has already occured)

P(B | A) = P(A and B)

                     -------

                      P(A)

If you subsitute in the values you get this:

P(B | A) = 0.10

               ------

               0.40

0.1 divided by 0.4 is equal to 0.25.
