Answer:
86°
Step-by-step explanation:
Normally, the building stands at an angle of 90° to the ground (from horizontal)
so,
x = 90° - 4° = 86°
X and 4° are complementary angles then their sum will be 90°.
[tex]\\ \sf\longmapsto x+4=90[/tex]
[tex]\\ \sf\longmapsto x=90-4[/tex]
[tex]\\ \sf\longmapsto x=86°[/tex]
