Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

so we know that pi=180 (in radian)

thus then pi/4=180/4=45 degrees

pi/3=180/3=60 degrees

hence angle b=30 degrees

angle a=45 degrees

so here c ie side opp.to angle c ie ab=2

so thus then side opposite to angle a is bc and opp.to b is ac

hence so here after applying angle sum property we would get angle c=75 degrees

so here angle c is biggest angle

so we know that side opp.to greater angle is the greatest side

hence then side opp.to angle c is ab

thus then ab is our hypotenuse

so applying first sin B

we get

Sin B=AC/AB

so here angle b=30

thus then

Sin 30=b/c

1/2=b/2

ie b=1

now then using

tan A=BC/AC

here angle a=45

so thus tan 45=a/b

ie 1=a/1

hence a=1
