Answer:
Obtuse triangle
Step-by-step explanation:
<em>The longest side of the triangle is 26 in, so that will be the hypotenuse</em>.
By an extension of the Pythagorean theorem:
- <em>Right triangle: a² + b² = c²</em>
- <em>Acute triangle: a² + b² > c²</em>
- <em>Obtuse triangle: a² + b² < c²</em>
Where a and b are the legs, and c is the hypotenuse.
Plug in: 3.5² + 25² ₙ 26²
Powers: 12.25 + 625 ₙ 676
Add: <em>637.25 < 676</em>.
That means that this triangle is obtuse.
Answer:
in 
, 9 is not an even number, nor a multiple of 2, meaning 1,953,125 isn't a square number
Step-by-step explanation:
To find the volume you’ll need to multiply length*width*height
your length= 4ft
your width= 4ft
your height= 5ft
so now multiply
4*4*5= 80ft^3
Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
