B is opposite __________.
sukhopar [10]

Answer: OPTION D.

Step-by-step explanation:

By definition, the opposite side of a triangle is that side that is on the opposite direction of an angle.

As you can see, the triangle ABC shown in the figure attached in the problem has the angles: ∠A, ∠B and ∠C.

Then, the angle ∠A is opposite to BC, the angle ∠B is opposite to AC and the angle ∠C is opposite to AB.

Therefore,  you can conclude that the answer is the option D, which is: AC.

Tell whether the triangle with the given side lengths is a right triangle
Andreas93 [3]

Answer:

not a right triangle

Step-by-step explanation:

The Pythagorean Theorem states that If a triangle is a right triangle,

the hypotenuse^2 will equal to shorter^2 + longer^2

hypotenuse = 18, shorter side = 4, longer side = 17

18^2 = 4^2 + 17^2

324 = 16 + 289

324 = 305

That is false, therefore the triangle is not a right triangle

What is the area of this triangle?
amid [387]
We can solve for the 3 triangle sides.
The left side is easy 6.
Second side² = 7² + 4²
Second side² = 49 + 16
Second side = square root (65)
Second side = <span> <span> <span> 8.0622577483 </span> </span> </span>
Third Side² = 7² + 2²
Third Side² = 53
Third Side = <span> <span> <span> 7.2801098893 </span> </span> </span>
When we know 3 sides, we use Heron's formula for calculating area:
Perimeter = <span> <span> <span> 21.3423676376 </span> </span> </span>
Semi-Perimeter = <span> <span> <span> 10.6711838188 </span> </span> </span>
Using Heron's Formula
area = square root (<span>10.6711838188 * </span><span>4.6711838188 * </span> <span> <span> <span> 2.6089260705 </span> </span> </span> * <span> <span> <span> 3.3910739295 </span> </span> </span> )
area = square root (441)
area = 21

Yes, it's just that "easy".  LOL
