i) cos A = cos B
ii) tan A = tan B​

Answer 1

Answer:

In triangle ABC, right angled at LC, given LA = LB find

i) cos A = cos B

ii) tan A = tan B

G

Answer 2

Answer:

Hence,

Here I proved that :

(i) cosA=cosB

(ii) tanA=tanB

Step-by-step explanation:

Before starting the first part in the pic,

we need to find the length of Hypotnuse AB:-

AB^2= BC^2+AC^2

AB =√x^2+x^2

AB =√2x^2

AB = x√2

Rest is clear in the pics

Hope this helped you...
