First let's calculate the sides opposite the angles.
For this we will use the expression for the sine.
In a right angled triangle, the sine of an angle is:
The length of the side opposite the angle divided by the length of the hypotenuse.
The abbreviation is sin
sin θ = opposite / hypotenuse
[tex]\begin{gathered} AB=h\cdot\sin (29) \\ AB=4.84 \\ \\ CB=h\cdot\sin (61) \\ CB=8.74 \end{gathered}[/tex]
The perimeter of a triangle is simply the sum of its three sides.
[tex]\begin{gathered} P=10+8.74+4.84 \\ P=23.6 \end{gathered}[/tex]
The perimeter would be 23.6
