Is 21,28,35 a right triangle?

I will mark the CORRECT answer Brainiest.

Answers

Answer:

Yes

Step-by-step explanation:

If the sides match Pythagoras' Theorem, the triangle is a right triangle.

$21^(2) +28^(2)$

= $441+784$

= $1225$

= $35^(2)$

Answer:

Yes

Step-by-step explanation:

Criteria for finding a right triangle is that sum of square of two sides = square of the third side.

Let the sides be A, B and C.

( i.e )

A² + B² = C²

So,

Let,

A = 21

B = 28

C = 35

21² + 28² = 35²

441 + 784 = 1225

1225 = 1225

Hence,

Sides 21, 28, and 35 will form a right triangle.

Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationale.2/3x + 3/4 = 8 8x=87

Answers

Answer:

The two equation have the same solutions.

Step-by-step explanation:

Consider the provided equations.

$(2)/(3)x + (3)/(4) = 8$ ......(1)

$8x=87$ .......(2)

We need to determine whether or not the two equations below have the same solution.

Solve the first equation.

$(2)/(3)x + (3)/(4) = 8$

Multiply both the sides by 12.

$2x(4) + 3(3)=96$

$8x + 9=96$

$8x=96-9$

$8x=87$

Here we can observe that after simplifying the first equation both the equation becomes the same.

Hence, the two equation have the same solutions.

No they don't. 2/3=.67, 3/4=.75. 8-.75=7.25. 7.25/.67=10.82.... 87/8=10.88 :) hope this helps
