Answer:
<h2>The triangle is scalene.</h2>Step-by-step explanation:
The given problem states:
<em> "A circle is inscribed in the triangle so that three of the six resulting segments of the tangents are 3 cm 4 cm 5 cm. Determine the type of triangle"</em>
<em />
The triangle is scalene, because of the tangents produce non-equal parts between sides, it means that the whole three sides are also non-equal.
In the image attached, you can see better this problem with the sides of the triangle, which are 7 cm, 8 cm and 9 cm, respectively to parts 3 cm, 4 cm and 5cm.
Therefore, the triangle is scalene.
Answer:
B
Step-by-step explanation:
Consider the rule of radicals
×
⇒
Given
4 ← substitute x = 9
= 4
= 4( ×
)
= 4( × 3)
= 12
Thus the value of x is 9
