Question

Can someone help me with the question, please.

Answer 1

x = arcsin 0.591 = 0.632 radian or 36.21 degrees

Explanation:

Angle x and the sides 13 and 22 cm are related through the sine function as follows:

opposite side 13 cm

sin x = ---------------------- = ------------- = 0.591

hypotenuse 22 cm

Now find x using the inverse sine function:

x = arcsin 0.591 = 0.632 radian or 36.21 degrees

Answer 2

36.22°

Solution,

Perpendicular = AB

hypotenuse = AC

we know that,

`sin \: theta = (perpendicular)/(hypotenuse)`

`sin \: x \: = (ab)/(ac)`

`x = {sin}^( - 1) (13)/(22)`

`x = 36.22`

Hope this helps...
