Answer:
So, BC = 5.6 cm
Step-by-step explanation:
Since its a right angled triangle,
taking 62 as reference angle,
cos62 = b/h
or, cos62 = AB/BC
or, cos62 = AB/12cm
or, cos62×12cm = BC
so, BC = 5.63
Number of miles traveled by light in a light-year is 5.952 × 10^12 miles
Step-by-step explanation:
- Step 1: Find the number of miles (distance) in a light year by using the formula for speed = Distance/Time
⇒ Distance = Speed × Time
= 1.86 × 10^5 × 1 yr (convert to seconds)
= 1.86 × 10^5 × 365 days × 24 hrs × 60 mins × 60 sec
= 1.86 × 10^5 × 31,536 × 10³
= 1.86 × 3.2 × 10^5 × 10^7
= 5.952 × 10^12 miles
Answer:
Step-by-step explanation:
Answer:
12x<180
14
Step-by-step explanation:
12x<180
x<180/12
x<15
Since x has to be less than 15, he took at most 14 people.
