SOLUTION:
= ( 7 / 8 )m + 9 / 10 - 2m - 3 / 5
= - ( 9 / 8 )m + 3 / 10
Answer:
5/12
Step-by-step explanation:
All of the other answers share at least one factor they can be divided by (the numerator in all cases). 5/12 however shares no factors and cannot be simplified anymore.
No, they are the same value.
Given:
In a right angle triangle ABC, altitude BD drawn to hypotenuse AC.
AD=3 and, AC=27.
To find:
The length of AB.
Solution:
Draw a figure by using the given information as shown below.
In triangle ABC and ADB,
(Right angles)
(Common angle)
(AA similarity postulate)
We know that the corresponding parts of congruent triangles are proportional. So,

After substituting the given values, we get



Taking square root on both sides, we get


Therefore, the length of AB is 9 units.
