Find y. image of a triangle whose lower left corner has a box and upper left corner is labeled 30 degrees; the vertical side of the triangle is labeled y and the horizontal side is labeled 9 A. 4.5 B. 18 C. 9 D. 9 times the square root of 3
Im pretty sure, this is a 30 60 90 triangle. so the sides are labled 2a, a, a\[1.)2a\] \[2.) a\] \[3.) a \sqrt{3}\]
I believe the answer your looking for is D.) \[9\sqrt{3}\]
30-60-90 triangle, so: a is shortest side = 9 here 2a is hypothenuse = 18 here a*sqrt(3) is 3rd side = 9√3 here Hint: Do make a good drawing, with the proper angles (30, 60, 90). It helps identifying this is a special triangle!
