Answer:
B
Step-by-step explanation:
From the figure, we can say:
∠NFG + ∠EFN = ∠EFG
We substitute the given measure and write:
6x + 4 + 24 = 12x - 2
Now, we simply solve this algebraically for "x". Shown below:

x is 5, so B is the correct answer.
Answer:
1
Step-by-step explanation:
sin²x = (sinx)²
cos²x = (cosx)²
Step 1: Define
sin²45° + cos²45°
Step 2: Rewrite
(sin45°)² + (cos45°)²
Step 3: Evaluate
sin45° = √2/2
cos45° = √2/2
(√2/2)² + (√2/2)²
1/2 + 1/2
