Answer with explanation:

It is given that the triangle has three sides having side length 2, 2 and 3 units.

Since two sides of triangle is equal, So it is an Isosceles triangle.

To check whether it has any of the angle is right angle or Obtuse angle, we will use Cosine formula.

Since Angle Opposite to Larger side is greater.Angle Opposite to Larger side 3 units be m°.

$\cos m=\frac{2^2+2^2-3^2}{2\times2 \times 2}\\\\\cs m=\frac{4+4-9}{8}\\\\ \cos m=\frac{-1}{8}$

⇒→Since , cosine of angle between two sides ,2 and 2 is , Negative.It means it is an Obtuse Angle.

So, other two angles will be acute.

So, the given triangle having sides 2,2,and 3 is Obtuse Isosceles Triangle.

8.EE.1.2

Semenov [28]

Considering that the square root of 9 is of 81 and of 10 is of 100, we have that the expression that has a value between 9 and 10 is given by:

B.) √89

E.) $\sqrt[3]{750}$

F.) $\sqrt[3]{999}$

<h3>How the square root of a number is used to solve this question?</h3>

We suppose numbers n and m, with square roots given, respectively, by n² and m².

Then, the square roots of all numbers between n² and m² have values between n and m.

In this problem, the square roots are given by:

9² = 81.

10² = 100.

Hence, the square root of all values between 82 and 99 are values between 9 and 10, thus option B is correct.

As for the cubic root, we apply the same logic and have that:

9³ = 729.

10³ = 1000.

Hence options E and F are also correct, as the values between 730 and 999 have cubic roots between 9 and 10.

Who will solve this attached picture problem correctly they will be marked as Brainliest answer.

Elodia [21]

Answer:

no it isn't

Step-by-step explanation:

if you find all of the angles using the angle addition postulate and supplementary angles rule (add to 180 degrees), you will be left with an angle that is not able to satisfy either of these rules, 75 $\neq$ 60

50 decreased by 26 percent

Phoenix [80]

50 decreased by 26 percent is 37 how all u have to do is

26/100 and X/50
Cross multiply and get
100X=1300
now divide by 100 and get 13
Subtract 50 by 13 and get 37

It can consist of translations (slides), reflections (flips), and rotations (turns).

I would say a reflection, then slide right, then slide down.

If A and B are 7 x 2 matrices, and C is a 4x7

Nata [24]

Answer:

A, B, D, F

Step-by-step explanation:

Matrix operations require that the matrix dimensions make sense for the operation being performed.

Matrix multiplication forms the dot product of a row in the left matrix and a column in the right matrix. That can only happen if those vectors have the same dimension. That is the number of columns in the left matrix must equal the number of rows in the right matrix.

Matrix addition or subtraction operates on corresponding terms, so the matrices must have the same dimension.

The transpose operation interchanges rows and columns, so reverses the dimension numbers. It is a defined operation for any size matrix.

<h3>Defined operations</h3>

A. CA ⇒ (4×7) × (7×2) . . . . defined

B. B -A ⇒ (7×2) -(7×2) . . . . defined

C. B -C ⇒ (7×2) -(4×7) . . . undefined

D. AB' ⇒ (7×2) × (2×7) . . . . defined

E. AC ⇒ (7×2) × (4×7) . . . undefined

F. C' ⇒ (7×4) . . . . defined
