Answer: no

Step-by-step Explanation: If the sum of the squares of two sides of a triangle is equal to the square of the third side or a² + b² = c², then the triangle is <u>right</u>.

In this problem, we're given a triangle that has

sides with lengths of 11, 13, and 17.

Let's plug these lengths into the pythagorean theorem.

(11)² + (13)² = (17)² or 121 + 169 = 289.

Since 121 + 169 ≠ 289, this is not a right triangle.

Answer:

Step-by-step explanation:

We can use the Pythagorean theorem to check

a^2 +b^2 = c^2

11^2+13^2 = 17^2

121+169 =289

410 does not equal 289

This is not a right triangle

Which expression could help you find the distance between (10,4) and (-6,4) ?

lina2011 [118]

Answer:

Option D. |10| + |-6|

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

(10,4) and (-6,4)

substitute

$d=\sqrt{(4-4)^{2}+(-6-10)^{2}}$

$d=\sqrt{(0)^{2}+(-16)^{2}}$

$d=16\ units$

therefore

The expression that could help to find the distance is

$|10| + |-6|=10+6=16\ units$

Nghiep gave his mother half of his weekly earnings and then spent half of what was left on a new shirt. He then had $34. What we

rusak2 [61]

Answer:

Hence the weekly earnings of Nghiep= $136

Step-by-step explanation:

Let the weekly income of Nghiep be $ x.

As it is given that:

Nghiep gave his mother half of his weekly earnings i.e. the amount he gave to his mother= $ (x/2).

So now we will be left with= $(x/2).

Next he then spent half of what was left on a new shirt.

so the amount he spent on his shirt= $ (x/4)

Now he will be left with = $ (x/4).

Now it is given that the amount he had after spending on his shirt and giving to his mother= $ 34

i.e. $\dfrac{x}{4}=34\\\\x=34\times 4\\\\x=136$

Hence, the weekly earnings of Nghiep= $136.
