PLS FAST In a right triangle, angle A and angle B are acute, find the value of sinB given tanB=4/3.

sinB= 4/5

Step-by-step explanation:

tan= opposite/ adjacent

3^2+4^2= hypotenuse^2 so hypotenuse=5

sin= opposite/ hypotenuse

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:
