2. Gwen walks 25 feet away from her house and places a mirror on the ground. She backs 7 feet away from the mirror so that she can see the tip of the roof. Gwen's eyes are 5 feet above the ground. Gwen and the house are both perpendicular to the ground. The angles between the top of the house, the mirror, and the ground and between Gwen's eyes, the mirror, and the ground are
congruent as shown in the image below:

What is the height of the house? Show your work and explain your reasoning in complete sentences. (10 points)

Which of these triangle pairs can be mapped to each other using two reflections?

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
