Trigonometry homework!! im struggling

Answer 1

`13.834\ units`

Explanation:

`We\ are\ given,\\A\ right\ triangle\ with\ one\ of\ it's\ angles\ as\ 70,\ and\ the\ hypotenuse\ as\ x\\ and\ the\ height\ as\ 13.\\Now,\\We\ know\ that,\\With\ respect\ to\ any\ angle\ A,\\sin A=(Opposite)/(Hypotenuse)\\ Hence,\\Here,\\sin\ 70=(Side\ opposite\ to\ 70)/(Side\ opposite\ to\ 90) \\ sin\ 70=(13)/(x)\\ Since\ sin\ 70\ degrees \approx 0.94,\\0.94=(13)/(x)\\ Hence,\\We\ finally\ get:\\x=(13)/(0.94) =13.834\ units`
