By the angle bisector theorem, one of the lengths of the third side of the triangle is given by:
1.5 / 1 = x / 2.6
x = 1.5 x 2.6 = 3.9
One of the possible length of the third side is 3.9 cm
The other possible length is given by 1 / 1.5 = x / 2.6
1.5x = 2.6
x = 2.6/1.5 = 1.7
The other possible length of the third side is 1.7 cm.
Answer:
Step-by-step explanation:
Alberto is correct in reasoning that all lines and rays are congruent to each other but incorrect in his reasoning about the line segments.
Line segments are equal in measure only when they are equal in length. They can have any orientation on a plane.
Since, AB = 3 units
CD = 4 units
Therefore, AB ≠ CD
Error in AB ≅ CD
Answer:
+2
Step-by-step explanation:
=> 
=> 
<em>Arranging it in descending order</em>
=> 
<u><em>So, the coefficient of x² in this expression is +2</em></u>
The least common denominator is 5y, and can be obtained by multiplying
-1/y by 5/5 to get -5/5y.
If we add the numbers using the least common denominator, we get:
-5/5y + 2/5y = -3/5y
