A and D can be automatically eliminated since the a side cannot be longer than the hypotenuse in a triangle.
Recognize that the two triangles are similar triangles, you get
2.7/3.6 = h/1.5 => h = 1.125.
180-93.5=86.5
x=86.5:2=43.25
The Answer would be B 30 because the triangles are equal to each other so you divide the 60 by 2
They’re the coefficients of the unknown numbers
