Using the sine ratio in the right triangle
sin26° = =
( multiply both sides by 18 )
18 × sin26° = h , then
h ≈ 7.9 cm ( to 1 dec. place )
The angles A and B are alternate interior angles, and as such their measure is the same.
This leads to the equation
Subtract 4x and 6 from both sides to get
which simplifies to
Plug this value for in the expression for
to get
