Angles ∝ and β are the two acute angles in a right triangle. use the relationship between sine and cosine to find the value of ∝ if ∝ < β. ? sin(2x - 8) = cos(6x - 6)

Sin(2x-8)=cos(90-2x+8)=cos(6x-6).
So 98-2x=6x-6, 104=8x, x=13.
2x-8=18, 6x-6=72. The smaller angle is 18 and the larger angle is 72.

The vertex of the quadratic function is (1.5, -.75)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
