4/16 or 1/4 because 1 + 1 + 2 is 4 & 3 + 5 + 8 is 16 so the fraction will be 4/16 but u can also divide both by 4’s which is 1/4.
First step: Find how wide the bulletin board is
15 ft² ÷ 3 ft = 5 ft
Step the second: Use the perimeter formula P = 2l + 2w
P = 2(5) + 2(3)
<u>P = 16 ft</u>

Answer:
(b) Congruent Figures
Step-by-step explanation:
Reflections, rotations, and translations are called "rigid transformations" because they do not change the size or shape of the figure. The image is always congruent to the original.
On the other hand, dilations change the size of the figure, so the image is <em>not congruent</em> with the original.
Rigid transformations result in congruent figures.
1. Given
2. Same Side Interior Angles Theorem
3. Corresponding Angles Postulate
4. Substitution
Since triangle DEF = triangle JKL, m<D = m<J, m<E = m<K, m<F = m<L.
m<F = m<L = 90 degrees
m<K = m<E = 5(m<D)
but m<E + m<D = 90 degrees [right angled triangle]
5(m<D) + m<D = 90 degrees
6(m<D) = 90 degrees
m<D = 90 / 6 = 15 degrees.
