Yes other person is correct, it’s B!
Answer: 60 cm²
Step-by-step explanation:
This is pretty simple, we know AB is 12 cm and DE is 4 cm. We know ABC has a total of 180 square centimeters. So...
12 ÷ 3 = 4
180 ÷ 3 = 60
The answer is 60 cm²
I hope this helps!

Answer:
Step-by-step explanation:
I'm GUESSING you want to know a value for θ if possible
secθ + tanθ = cosθ/(1 - sinθ)
1/cosθ + sinθ/cosθ = cosθ/(1 - sinθ)
(1 + sinθ)/cosθ = cosθ/(1 - sinθ)
(1 - sinθ)(1 + sinθ) = cos²θ
1 - sinθ + sinθ - sin²θ = cos²θ
1 - sin²θ = cos²θ
1 = cos²θ + sin²θ
which is the unit circle, centered on the origin with radius 1 unit
0 ≤ θ ≤ 2π
I think the answer is negative 8 square root 726
then the answer if I am right sorry if I am not would be negative 88 square root 6
again sorry if wrong
