Answer 1

Answer:

x = 14.1 (Rounded to the nearest tenths)

Step-by-step explanation:

Since the opposite side of the angle given needs to be found out and hypotenuse, Sin ratio would be used;

Sin(42) = $\frac{x}{21}$

=> Now multiply 21 on both sides of =, in order to isolate x;

Sin(42) * 21 = x

14.1 = x

Hope this helps!

Answer 2

Answer:

14.1 =x

Step-by-step explanation:

Since this is right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth

14.1 =x
