Last question for math I need help ASAP!

a= 12, b= 24, c = 12, d= 12root3

Step-by-step explanation:

Because the triangle to the left is a right triangle with a 45 degree angle, we can deduce that it is a 45-45-90 special triangle where a =c. Furthermore, a and c = the hypotenuse divided by root 2.

12 root 2 / root 2 = 12

a=12, c=12

The triangle to the right is a right triangle with a 30 degree angle, so it is a 30-60-90 special right triangle.

If a = 12, b is 2 times a

b= 2*12 = 24

If a =12, d = a * root 3

d= 12root3

I hope this helped! :)
