b
Step-by-step explanation:
all you do is divide 10.2 by tan (67) and you get 4.33
Step-by-step explanation:

By calculator
Answer:
720
Step-by-step explanation:
60 minutes in a hour. So add 30 for each 20 minutes so it would be 90 an hour so multiply 90 by 8
Using Pythagoras theorem, we know that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The 5-foot side will fit to form a right triangle
<h3>How to use Pythagoras theorem to prove a right triangle?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
Therefore,
c²= a²+ b²
where
- c = hypotenuse side
- a and b are the other legs.
Therefore,
3² + 4² = 5²
Hence,
Knowing that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The 5-foot side will fit to form a right triangle
