Answer:
108!
Step-by-step explanation:
The area of a trapezoid is
1/2 x h x (b1 + b2)
plug it in!
24 x 1/2 x 9
12 x 9
108
DE // BC
so AD/AB = AE/AC
The Triangle ADE is similar to triangle ABC
Answer is the first option
Triangle A ≡ Triangle A
Answer:
B y=54 degrees
Step-by-step explanation:
Since a triangle's angles always add up to 180.
180-72=108
108/2=54
It must be divided by two because y is two angles not one.
Answer:P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
