Given:
[tex]\begin{gathered} \angle A=58 \\ \angle B=90 \end{gathered}[/tex]
Find-: Elevation angle ( Angle c)
Sol:
The total angle of a triangle is 180.
[tex]\angle A+\angle B+\angle C=180[/tex]
Put the all value in the equation then:
[tex]\begin{gathered} \angle A+\angle B+\angle C=180 \\ 58+90+\angle C=180 \\ 148+\angle C=180 \\ \angle C=180-148 \\ \angle C=32 \end{gathered}[/tex]
So the angle of elevation is 32.
