Answer:
hi ther ...
Step-by-step explanation:
The theoretical probability will remain the same every time you do the experiment (50%), while the experimental probability will vary somewhat, since you probably aren't going to get 5 heads every single time.
The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.
Use cosine theorem to determine the cosine of the largest angle:
where 
is the largest angle.
Then
Since 
then
Divide this inequality by 5:
Note that 
then the smallest possible whole-number value of x is 7.
Answer: correct choice is B
1. Since it is an isosceles triangle, we know that the two length sides have to be the same. Therefore, the angles across from the sides are the same. They cannot be 90 degrees or above because 90+90+0 would mean we would have all the interior angles at 180 but the thing is the third angle cannot be zero. Therefore, the other two angles cannot be 90 or more. They must be acute.
Also, if it had two right angles (90 degrees) or more, it could not close to be a triangle.
Answer: D
Step-by-step explanation:
The construction of a triangle tangent to the three sides would require the construction of the incircle.
