• ﻿﻿﻿﻿Come with us and build a house with precise measurements.Help us solve for the right measurementsLet's Go!
• We know that the angle of inclination between the wall and floor is 30 degrees. The inclined length is 25 ft. To calculate the height we will use sin = (30) x/25/﻿﻿﻿﻿﻿.x/25.The height of the wall is 12.5 ft.
• We need to determine the height of the wall for the house﻿﻿﻿
• h = ﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿25ft ﻿
• ﻿30
• ﻿y
• x﻿﻿﻿﻿
• ﻿﻿We need to find the lenght of one side of the roof.
• We could use trigonometry to find the lenght. The ceiling is 15ft long, while the angle of the ceiling to the roof is 35°. We should use cos 35 = 15/h, h = 15/cos 35. The lenght of the roof is 18.3ft﻿﻿
• ﻿﻿o
• ﻿﻿﻿﻿﻿﻿a=15ft

• ﻿﻿﻿30
• ﻿We need to measure the distance between two windows, lets use trigonometry.﻿
• ﻿﻿If the side of the windows is 3ft high, and the angle of the top of one window to the bottom of the other is 20°, then we use tan 20 = o/3, o = 3 • tan 20. The distance between the two windows is 6.7ft
• ﻿h

• 20﻿
• ﻿a = 3ft﻿﻿﻿
• ﻿﻿Thank you for helping us!
