That answer would be like -10
0.158 < 0.58
0.58 is greater than one hundred fifty-eight thousandths.
You can compare the tenths place of both numbers to find out.
The measurement of the given angle is 30 degree.
Here we use trigonometric ratio rule which is sin theta= opposite/hypotenuse
Here theta = 30 degree, opposite =7 and hypotenuse =a
So we get
sin 30 = 7/a
a= 7/sin 30
And value of sin 30 = 0.5
So we get , a = 7/0.5 = 14
So the value of a is 14 .
