The triangles are similar by the SSS (side-side-side) similarity theorem because the sides of the two triangles are in proportion (5/15 = 3/9 = 4/12)
Hope this helps =)
9 / 60 = 0.15
To the nearest tenth is 0.2 miles per minute
Answer:
134.3
Step-by-step explanation:
In a right triangle, look at sides XW and XZ.
You now need to find XW.
In the measure of angle XZY (the one at the top) is 180 - (82 + 67) = 31 degrees.
Using the Law of Sines in triangle XYZ,
Put that into the equation for XW above...
A calculator shows that this is approximately 134.3
