Question

The length of AB in the given figure
​

Answer 1

right angle triangle

Step-by-step explanation:

the angle of 90*

Answer 2

Answer:

4cm

Step-by-step explanation:

In Triangles ABC and ADE,

LA = LA (COMMON)

LB = LD (BOTH 90)

therefore they are similar.

so AB/ AD = BC/DE

now calculating, let AB be x

therefore AB/AD (x/x+4) = BC/DE (3/6)

x/x+4 = 1/2

cross multiplicating,

2 * x = 1  *  x+4

4+x = 2x

4 = 2x-x

4=1x

therefore, x is 4 and so is AB.

Thankyou
