Answer:
15*(1+root(3))
Step-by-step explanation:
BD=5, BC=5*root(3), you can find it by using trigonometry.
AC^2=300, AC=10*root(3)
AB^2=225, AB=15.
Perimeter of ABC is AB+BC+CA=15+5*root(3)+10*root(3).
15(1+root(3))
Answer:
slope=4/5
y-intercept = -3
Step-by-step explanation:
first we need to rewrite the expression to

were b is the y-intercept and m the slope

so there we have it

Answer:
there are no instructions
Step-by-step explanation:
pls fix ur question
Answer:
9 = x (assuming 15 is the hypotenuse)
Step-by-step explanation:
15^2 = 12^2 + x^2
225 = 144 + x^2
subtract 144 from both sides
81 = x^2
square root both sides
9 = x
