Answer:
A.
Step-by-step explanation:
Route the images in your mind. A. is a 180° view of H.
63+74+x=180
180-63-74=43
x=43
4n - 8 = n + 13
4n - n = 13 + 8
3n = 21
n = 21/3
n = 7....the number(n) = 7
Answer:
-2.46
Step-by-step explanation:
-12.41+9.95=-2.46
Area of a sector (s) = radius (r) · θ (in radians)
First, convert 168° into radians using the proportion π = 180°



Next, plug in x for θ
s = r · θ
= 8 ·

=

= 23.457
≈ 24.0
