sum of all sides of triangle=180°
7x+13x+16x=180°
36x=180°
x=180°/36
x=5
angle D=7x
=7(5)
D=35°
angle E=13(x)
=13(5)
E=65°
angle F=16x
=16(5)
F=80°
angle D=35°
angle E=65°
angle F=80°
There isn't a b variable in this equation, but x = 2.5. (:
Answer: Only the second image
Step-by-step explanation:
Both methods start out with a factor<span> tree. A </span>factor<span> tree is a diagram that is used to break down a number into its </span>factors until<span> all the numbers left are </span>prime. The first way you can use a factor<span> tree to find the </span>factorization of a number is to divide out prime<span> numbers only. Let's </span>factor<span> 24 using this method.</span>
