The base of given triangle is 8 cm.

Further explanation:

The area of triangle is calculated by using two methods

  • Hero's formula
  • Base and Height

Hero's formula requires all three sides of triangle while we can use only base and height in second formula.

Given

A = 20\ cm^2\\h = 5\ cm

As the area of triangle and height are given, then

A = 0.5*b*h\\20=0.5*b*5\\20=2.5b\\b=\frac{20}{2.5}\\b=8\ cm

The base of given triangle is 8 cm.

Keywords: Area of triangle, base, height

A drug trial is testing the effectiveness of two drugs. If 50 patients are given Drug A, 20 patients are given Drug B, and 100 p
Vsevolod [243]
So, to find the answer you'd first add up how many patients you have:
20+50+100 = 170.
In a fraction your total would go on the bottom. Then you'd take how many patients are taking a real drug, which is represented by 20+50 = 70. This number would go on top.

So, the probability of a patient NOT getting a placebo is 70/170. Simplified would be 7/17. 

The answer is D. 7/17.

The side lengths of a triangle are 5, 8, and 12. Is this a right triangle?
professor190 [17]

Answer:

A) No...

Step-by-step explanation:

We can check if this triangle is a right triangle by using the Pythagorean Theorem.

  • a² + b² = c²
  • where a and b are the legs of the right triangle, and c is the hypotenuse (longest side)

Using 5 for a, 8 for b, and 12 for c, let's see if this satisfies the equation:

  • 5² + 8² = 12²

Simplify.

  • 25 + 64 = 144
  • 89 = 144

We can see that 89 ≠ 144, so this leaves us with answer choices A and B. I think you meant to write < for the last + sign.

Seeing as the sum of the two lengths of the triangle is greater than the third side length, this creates a normal triangle. This cannot be the correct answer choice since this only satisfies the requirements for a triangle, but not a right triangle.

This leaves us with answer choice A.  52 + 32 ≠ 122 and 52 + 32 < 122. (I'm not sure why the squares of the side lengths are not used, but this should be the correct answer.)
