Daniela climbed to the top of a 164 foot lighthouse and spotted a water fountain on the ground below. If the angle of depression fro the lighthouse to the fountain is 54 ° , how far is the fountain from the base of the lighthouse?

Which expression is equivalent to 2x^2+7x+4?

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
