To find the length of side a, we can use the sine function. The sine of angle C is equal to the length of the side opposite angle C (side a) divided by the length of the hypotenuse (side h).
sin(C) = a/h
Substituting the given values:
sin(39°) = a/10
To find the length of side a, we can rearrange this equation:
a = sin(39°) * 10
Using a calculator, we find:
a ≈ 6.23
Rounding to the nearest whole number, the length of side a is 6.
If
h=10
meters and
m∠C = 39°
, then what is the length of side
a
? Round your answer to the nearest whole number.
