If ΔABC≅ΔMNO, then what corresponding angle is congruent to angle N? (Enter your answer using the angle letter only.) (6 points)
Marysya12 [62]

Since they've already told us what triangles are congruent, all we have to do is match up the correct letters.

By CPCTC, angle N is congruent to angle B.

Hope this helps!

Good Question!

So since we know that a square is exactly the same all the way around we can assume that both diagonals in the square are the same. This means that they form a right triangle in the middle with two legs of 3.75!

So to find the side of the triangle we use a^2 + b^2 = c^2

3.75^2 + 3.75^2 = c^2
28.125 = c^2
<span>√(28.125) = c
</span>c = 5.3

Now finally we just square 5.3 again to find the area of the square and it's 28.1mm^2!

So the answer is the third one! hope this helps!

HELP PLZ! THIS IS TIMED.

Answer:

b_n=\dfrac{2}{3}\cdot (9)^{n-1}

Step-by-step explanation:

Given the geometric sequence

a_1=\dfrac{2}{3}\\ \\a_n=3a_{n-1},

then

a_1=\dfrac{2}{3}\\ \\a_2=3a_1=3\cdot \dfrac{2}{3}=2\\ \\a_3=3a_2=3\cdot 2=6\\ \\a_4=3a_3=3\cdot 6=18\\ \\a_5=3a_4=3\cdot 18=54\\ \\...

Hence,

b_1=a_1=\dfrac{2}{3}\\ \\b_2=a_3=6=\dfrac{2}{3}\cdot 9\\ \\b_3=a_5=54=\dfrac{2}{3}\cdot 9^2\\ \\...

Thus, the explicit formula is

b_n=\dfrac{2}{3}\cdot (9)^{n-1}

Answer:

x=1/3

Step-by-step explanation:

first you can simplify the 2 fractions (if possible) (2b-2/4 = b-3/8) in the fraction you can take out a 2 in the top binomial it will look like this 2(x-1)/4 then you can cancel out the 2 and that will leave you with x-1/2 = x-3/8 and  then you will multiply both denominators to the opposite side 8(x-1)=2(x-3) then get rid of the parentheses 8x-8=2x-6 then get the x's to one side by adding and 8 too both sides and subtracting 2x from both sides 8x-2x=-6+8 then combine like terms 6x=2 then divide the 6 you get 2/6 simplify and your final answer will be 1/3.
