use the trigonometri...

3. raden_zaikaria

let that angle is

4. raden_zaikaria

lat thet angle $\theta = a n g l e$

5. raden_zaikaria

tangen $\theta = \frac{ 190 feets }{ 190 feets}$

6. raden_zaikaria

tangen $\theta = 1$

7. raden_zaikaria

$\theta=\tan^{-1} 1$

8. raden_zaikaria

answer is $\theta= 45$

9. raden_zaikaria
