Find d.
Please explain if you know, thank you so much.

Step-by-step explanation:

the triangle is a 30º-60º-90º triangle, there's a formula for the sides of this type of triangle which I will attach

x = d

9 = x√3

9/√3 = x

x = 3√3

d = 3√3

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
