Ответ:
H =60 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan H = opp / adjacent
Tan H = 4 sqrt(33)/ 4 sqrt(11)
Rewriting
tan H = 4 sqrt(3) sqrt(11) / 4 sqrt(11)
tan H = sqrt(3)
Taking the inverse tan of each side
tan ^-1 tan H = tan ^-1 ( sqrt(3))
H =60
Ответ:
17.3 cm
Step-by-step explanation:
(refer to the attached for reference)
since the given triangle is a right triangle (i.e with one of the angles being 90 deg), we can use trigonometry to determine the missing side.
In our case, we are given ∠ABC = 68° and the length of its adjacent side AB = 7 cm.
From trigonometry, the following relationship may be formed:
tan (68°) = opposite length / adjacent length
tan (68°) = AC / AB
tan (68°) = AC / 7 (multiply both sides by 7)
7 tan (68°) = AC (rearrange)
AC = 7 tan (68°) (solve using calculator)
AC = 17.3256
AC = 17.3 cm (1 dec pl)
