please help and explain, will give BRAINLIEST! (also, use things like sin, cos, tan, pythagorean theorem, etc to solve please)

The triangle's altitude is 15

Step-by-step explanation:

Notice that triangle ABD is a right angle triangle, and therefore its sides should verify the Pythagorean theorem:

for this triangle the hypotenuse (b) is 47.43; side (a) is 45, and the last side (the segment BD) is our unknown (the triangle's ABC altitude). Then the Pythagorean theorem becomes:

which rounded will give 15

x = -2

y = 848
