Using relations in a right triangle, it is found that the length of AC is of 6.43 inches.
<h3>What are the relations in a right triangle?</h3>The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
In this problem, the length of side AC is b, which is opposite to the angle of 40º, while the hypotenuse is of 10 in, hence:

Mrs.smith divided one square mile of land to her 3 children,amy,brianna ,and chad.
1 mile is divided among each children . so the fraction of land each one get is
Amy's land =
Brianna's land =
Chad's land =
Amy decided to divide her portion of the land equally between her 2 children.

1/3 is divided among two children so we divide the fraction by 2
=
=
fraction of mrs. smith's land one of amy's children own.
Chad divided his land equally among his 6 children
We know Amys land = 1/3
1/3 is divided among 6 children so we divide the fraction by 6
