First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.

Altitude or height
Answer:
388.5/x
Step-by-step explanation:
multiply:
(-4004+2023-48-2)/ -4 + 2x +1
Simplify:
-2031/ -3 +2x
divide by -3
677/2x
388.5 / x
as simple as you can go
hope this helps!
