Step-by-step explanation:
x° + 61°+ 68° + 104° = 180°
x° + 129°+104°=180°
x°+133°=180°
x°=180°-133°
x=47°
Line through P(0, 5) and Q(-1, 8):
slope = m = (y2 - y1) / (x2 - x1) = (8 - 5) / (-1 - 0) = 3 / -1 = -3
line through R(3, 3) and S(5, -1):
slope = m = (y2 - y1) / (x2 - x1) = (-1 - 3) / (5 - 3) = -4 / 2 = -2
Parallel lines have equal slopes. Since the two lines have different slopes, they are not parallel.
Answer:
B
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = area of triangular face × length
Area of triangle =
bh ( b is the base and h the height )
Here b = 6 and h = 8, thus
Area =
× 6 × 8 = 3 × 8 = 24 units², thus
V = 24 × 20 = 480 units³ → B
