Question

I need help please.

Answer 1

Answer:

The measure of angle B is $67\°$

Step-by-step explanation:

we know that

Applying the law of sines

$\frac{a}{sin(A)}=\frac{b}{sin(B)}$

we have

$a=20\ units$

$b=32\ units$

$A=35\°$

substitute the given values and solve for B

$\frac{20}{sin(35\°)}=\frac{32}{sin(B)}$

$sin(B)=(32)sin(35\°)/20$

$B=arcsin((32)sin(35\°)/20)$

$B=67\°$
