Answer:
Option A
Step-by-step explanation:
In the given right angle triangle ABC,
BC = 15 m and m∠A = 55°
We have to calculate the measure of side AC.
Since tanA = [tex]\frac{Height}{Base}[/tex]
tan55 = [tex]\frac{15}{AC}[/tex]
1.428 = [tex]\frac{15}{AC}[/tex]
1.428(AC) = 15
AC = [tex]\frac{15}{1.428}[/tex]
AC = 10.5 m
Therefore, Option A. AC = 10.5 m is the answer
