giving brainliest determine the unknown angle measures of triangle DEF round the the nearest degree class=

Respuesta :

so using trigo ;

cos D =base/hypo
cosD =23.5/33.8 = 0.695

so and D = 45.97°

thus angle F = 180-(90+45.97) =44.03°

so your answers are 45.97° and 44.03° or you can say 45° and 45°....approx !!

The answer is:

m∠D = 46

m∠F = 44
