Hi! The answer to that question is B and D cause if you read the promblem it is it!
Answer:
length is 78
Step-by-step explanation:
Perimeter of rectangle is P = 2 (l +w)
278 = 2(l + 61)
l = 78
YZ= 2.8
3n+5=8n-9
-3n -3n
5=5n-9
+9. +9
14=5n
14÷5
2.8=n
s = rθ
70 in = (60 in) θ
θ = 7/6 radians
θ ≈ 1.167 radians
