Answer 1

Answer:

Step-by-step explanation:

GIVEN ; TAN A = 3/4

TAN = OPPOSITE SIDE / ADJACENT SIDE

THAT IS ; OPPOSITE SIDE = 3

ADJACENT SIDE = 4

USING PYTHAGORUS THEOREM ,

OPPOSITE SIDE²+ADJACENT SIDE²= HYPOTENUSE ²

3²+4²= HYPOTENUSE²

HYPOTENUSE²= 9+16

HYPOTENUSE ²=25

HYPOTENUSE = 5

TO FIND: SIN A COS A

SIN A= OPPOSITE SIDE / HYPOTENUSE

SIN A = 3/5

COS A = 4/5

SIN A *COS A= (3/5)*(4/5)

                      =12/25.

HOPE THIS HELPS.
