The only way to understand this is the 155 degree is the ladder turned or rotated keeping one end fixed, sweeping through 155 degrees, also making an angle on the acute part of 25 degrees. The ladder is no longer over the original position where it was, on the ground.

Now, you have a y number foot high side opposite of a 25 degree angle. One angle of this triangle is 90 degrees. The hypotenuse is 3 feet. You want to know y and the other leg.

y, the height
x, the leg on the ground
3%2Asin%2825%29=y
3%2Acos%2825%29=x
