Question

PLEASE GIVE THE ANSWER IF KNOWS.​

Answer 1

Answer:

1)90° 2) 3/4

Step-by-step explanation:

Sin A =1/2 so A is 30° and cosB=1/2 so B=60°

so 30+60=90

and the second is about renowned triangle ( Pythagorean triplet) 3,4,5

so cosA =4/5 so A=37° then tanA=3/4

Answer 2

Answer:

A = 45 B= 45

A+B = 45+45

= 90

Step-by-step explanation:

2) TAN A = 3/5
