State whether the given measurements determine zero, one, or two triangles. A = 80°, a = 24, b = 50
Arte-miy333 [17]
We know that
applying the law of sines
a/sin A=b/sin B---------> a*sin B=b*sin A
<span>A = 80°, a = 24, b = 50
sin B=[b*sin A]/a-----> sin B=50*sin 80/24-----> sin B=2.0517

the sines value </span><span>can not be greater than 1
hence

the answer is
zero triangles</span>
