A triangle has sides of lengths 16,14 and 50 .is the triangle right angle triangle?​
Debora [2.8K]

Answer:

no

Step-by-step explanation:

using the converse of Pythagoras' identity

If the square on the longest side is equal to the sum of the squares of the other 2 sides, then the triangle is right.

longest side = 50 ⇒ 50² = 2500

16² + 14² = 256 + 196 = 452

since 452 ≠ 2500 then the triangle is not right

The perimeter of a rectangle changes from 2.5 to 10 after dilation what was the scale factor of the dilation
yan [13]
The scale factor is 4 (10/2.5).

Each side has increased by a factor of 4. Think of it logically, if the original rectangle had sides of 1,1,1/4,1/4, the perimeter would add to 2.5. In order to get the sides to add up to 10, each of the sides would need to be multiplied by 4. Then our sides would measure 4,4,1,1 with a perimeter of 10.

17-5(2×-9)=-(-6×+10)+4<br><br><br><br><br> Please help me with this problem
uranmaximum [27]

Answer:

  x = 17/4 = 4.25

Step-by-step explanation:

We assume your multiplication symbol (×) is intended to be a variable (x).

Simplifying, we have ...

  17 -10x +45 = 6x -10 +4

  68 = 16x

  68/16 = x = 17/4 = 4.25

__

<em>Check</em>

17 -5(2(4.25) -9) = -(-6(4.25) +10) +4

17 -5(8.50 -9) = -(-25.5 +10) +4

17 -5(-0.5) = 15.5 +4

17 +2.5 = 19.5 . . . . . . true
