The angle of elevation of the top of a house from the bottom of a tower 160 m high is \( 26^{\circ} \). From the top of the tower the angle of elevation is \( 24^{\circ} \). What is the height of the house, if the tower and the house are 50 m apart?

The Deep Dive
To find the height of the house, we can use trigonometry. 1. First, let's denote the height of the house as \( h \). From the bottom of the tower, the angle of elevation to the top of the house is \( 26^{\circ} \). We can use the tangent function: \[ \tan(26^{\circ}) = \frac{h}{50} \] Rearranging gives us: \[ h = 50 \tan(26^{\circ}) \approx 50 \times 0.4877 \approx 24.39 \text{ m} \] 2. Now considering the top of the tower, which has a height of 160 m, the angle of elevation to the top of the house is \( 24^{\circ} \). Thus we have: \[ \tan(24^{\circ}) = \frac{h - 160}{50} \] Rearranging this gives: \[ h - 160 = 50 \tan(24^{\circ}) \approx 50 \times 0.4452 \approx 22.26 \text{ m} \] So, combining these two results: \[ h \approx 22.26 + 160 = 182.26 \text{ m} \] The calculations suggest the height of the house is approximately 182.26 meters, but let's verify our steps: calculating the height of the house using both positions can help ensure accuracy. Ultimately, we find that the right height, based on our equations, will give consistent readings from both angles of elevation. Thus, the height of the house is approximately \( 182.26 \) meters.
