It should be B based off the shaded area
Answer:
10 hours, 30 minutes.
Step-by-step explanation:
Distance ÷ Speed = Time
525 ÷ 50 = 10.5
12%
40% = 0.4
30 = 0.3
0.3 x 0.4 = 0.12
0.12 = 12%
30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.
3k+7k+8k=180
18k=180
k= 10
Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.
