6. From a point level with the base of a water tower, the angle of elevation to the bottom of the
water tank is 389 and to the top of the water tank is 47°, If the water tank itself is 20 feet
high, what is the height of the tower and tank together? Show your work.

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 =

The trigonometric ratios sine and secant are reciprocals of each other
