Answer:
18
Step-by-step explanation:
Assuming the sides are 12 and 38
Since this is a right triangle, we can use trig functions
We know the opp side and the adj side of the angle in questions
tan ? = opp /adj
tan ? = 12/38
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (12/38)
?=17.52556
To the nearest degree
? = 18
If the side is 36,
tan ? = opp /adj
tan ? = 12/36
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (12/36)
?=18.43494
To the nearest degree
? = 18
