Question

if sinA= 3/5and cosA=4/5 find the value of sin square A + cos square A​

Answer 1

Answer:

1

Step-by-step explanation:

sin a = 3/5

sin square a=3/5 square=9/25

cos a= 4/5

cos square A=4/5 square=16/25

so

sin square a+cos square a =

9/25 + 16/25

= 25/25

= 1

Answer 2

SOLUTION:-

Given:

⚫sinA= 3/5

⚫cosA= 4/5

Therefore,

The value of sin²A + cos²A.

$= > ( { \frac{3}{5} )}^{2} + ( \frac{4}{5} ) {}^{2} \\ \\ = > \frac{9}{25} + \frac{16}{25} \\ \\ = > \frac{9 + 16}{25} \\ \\ = > \frac{25}{25} \\ \\ = > 1$

Hope it helps ☺️
