1. <A= sin a/c

= sin 26/31

=sin 0.8387=57degree

<A= 57degree

2.<B= cos a/c

= cos 26/31

= cos 0.8387=33degree

<B = 33degree

3.<C=90 degree cause it already gave us the sign of perpendicular sign

4. B=(c^2 - a^2)square root

=(31^2-26^2)square root

=(961-676)square root

=(285)square root

B=


√(285)

if you have a question ask me in private or comment chat
