Question

Which equation can be used to solve for angle A?

sin (A)
2.4
sin (110°
4.6
sinca) = sin (1109
sin.ca - sin (1209
sin
sin (110
4.6
2.4
sin (A) - sin (110)
3.2
4.6
sin (A) - sin (1109)
4.6
3.2

Answer 1

it’s c

Explanation:

Answer 2

C

By the law of sines,
`(sinA)/(a)=(sinB)/(b)=(sinC)/(c)` where A, B, C are the angles and a, b, c are the lengths of the sides opposite their respective angles. In this case,
`110^(\circ)` is opposite 4.6 and A is opposite 3.2, so
`(sinA)/(3.2)=(sin(110^(\circ)))/(4.6)`, giving the answer.
