Answer:
16.3 rounded to the nearest tenth
Explanation:
The formula for the sine rule is Sin A / a= Sin B / b = Sin C / c which is as, Sin V / v = Sin X / x = Sin S / s
Sin 90 / 25 = Sin X / 7, that is,
1 / 25 = Sin X / 7 (cross multiply)
Make Sin X the subject of the formula;
Sin X = 7 / 25
X = Sin^-1(7 / 25)
X = 16.26 = 16.3 rounded to the nearest tenth
