Answer:
A. 103 degrees
B. 77 degrees
C. 60 Degrees
Step-by-step explanation:
A. Triangles' interior angles add up to 180, so if you already have 2 angles you just need to put them together, and subtract them from 180.
47+30=77
180-77=103
B. Lines also are 180, so 103-180=77
C. Interior angles of a triangle add up to 180, so 180/3 is how you get your answer.
Answer:
The compound inequality:
30 ≤ 2L + 2w ≤ 64
w < 12
The range:
3 ≤ w < 12
Step-by-step explanation:
Let L be he length , w the width and p the perimeter
p=2L + 2w
30 ≤ p ≤ 64 ⇌ 30 ≤ 2L + 2w ≤ 64 ⇌ 30 ≤ 24 + 2w ≤ 64 ⇌ 6 ≤ 2w ≤ 40
⇌ 3 ≤ w ≤ 20
but ,since the width is less than the length then w < 12
then 3 ≤ w < 12
