Find AB.In Exercise 3,CB炉 is tangent to 鈯�A.

Short Answer

Expert verified

The length of,AB=92.

Step by step solution

01

Step 1. Given information.

The figure here given is,

02

Step 2. Concept Used.

cosA=leg adjacent to鈭�Ahypotenuse

03

Step 3. Consider the given figure for further solution.

From the above figure it is clear that this triangle is a 45-鈭�45-鈭�90掳triangle.

So,

m鈭�CAB=m鈭�CBA=45

Consider the right triangle 螖OTJ.

cosCAB=legadjacentto鈭�TOJhypotenusecos45掳=CAAB12=9AB

04

Step 4. Now perform cross multiplication.

AB=9脳2AB=92

Therefore,the length of,AB=92.
