Answer:
x=7
y=7√3 or 12.124355653
Step-by-step explanation:
a special triangle 30-60-90 ==== 1:2:√3
or the missing angle = 180-90-30=60⁰
so: the sides will be.
a=x, b=y=x√3, c=2x = 14
let's solve for x using the hypotenuse:
2x=14
x=14/2=7
so the sides will be:
y=x√3=7√3 or 12.124355653
c=14
using sin30 and cos30
sin 30 = x/14
x = 14 sin30 = 7
cos 30 = y/14
y = 14cos30=12.124355653
