Answer:
150
Step-by-step explanation:
Rate at which volume decrease:
(1 × 2 × 20/100) ÷ 30
= 1/75 m³/min
Total volume:
½ × (1.4 + 0.6) × 2 × 1
= 2 m³
Time = 2 ÷ 1/75
= 150 mins
A cuboid has 8 vertices and 12 edges
The answer is D 1/2
Cos of 60 = 0.5
Which 0.5 as a fraction is 1/2
We know that
in the triangle ABC
∡A+∡B+∡C=180°
∡C=180-(50+100)-------> ∡C=30°
triangle ABC and triangle XYZ are similar
so
∡X=∡A
∡Y=∡B
∡Z=∡C
hence
∡Z=30°
the answer is∡Z=30°
