Question

:))))))) i hate math please help

Answer 1

a = 19.9

Explanation:

Sine rule: Sine rule states the relationship between the angles and their opposite sides of the triangle.

`\boxed{\bf (a)/(Sin \ A)=(b)/(Sin \ B)= (c)/(Sin \ C)}`

A = 64°; b = 17; B = 50°

`\sf (a)/(Sin \ 64^\circ)=(17)/(Sin \ 50^\circ)\\\\(a)/(0.8987)=(17)/(0.766)\\\\~~~~~~~~~a =(17)/(0.766)*0.8987\\\\\\~~~~~~~~\boxed{\bf a = 19.9 }`
