Answer:
The value of A is 60.1°
Step-by-step explanation:
You have to use Trigonometric formula, sinθ = opposite/hypotenuse. Then substitute the following value into the formula,
[tex] \sin(θ) = \frac{oppo.}{hypo.} [/tex]
Let θ = a,
Let oppo. = 13 units,
Let hypo. = 15 units
[tex] \sin(a) = \frac{13}{15} [/tex]
[tex]a= { \sin( \frac{13}{15} ) }^{ - 1} [/tex]
[tex]a =60.1 ° \: (1d.p)[/tex]
