Can someone explain how to do this?

Sum of (15x-2) and (7x+4) will be 90° as it is tight angled triangle.

So, 22x+2 = 90

22x = 88

x = 4

So, major angle BAC = (360-58)° = 302°

And major angle CAD = 360° - 32 = 328°

i hope this is what you were looking for.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
