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.
About $80
5.29*16.3=86.227 which is closest to 80
You would use the y-intercept and slope because y-intercept form is the easiest way to graph. you just plot the y-intercept and draw the line with the correct slope.
