Elouise and Marcus are 20 km apart. There is a lake due west of Elouise that is also 10√3 km due north of Marcus, so 22.36 km distance the bearing of Marcus from Elouise.
<h3>What is Pythagoras theorem?</h3>
According to the Pythagoras theorem, the square of the hypotenuse of a right-angled triangle equals the sum of the squares of the other two sides. The formula for this theorem is c² = a² + b², where c is the hypotenuse and a and b are the triangle's two legs. Pythagoras theory triangles are another name for these triangles.
At first assume a triangle, In the triangle, assume Elouise at the point A and Marcus at the point B, and the lake at the C point.
Given that,
Elouise and Marcus are 20 km apart (AB)
There is a lake due west of Elouise that is also 10√3 km due north of Marcus (BC)
Now, according to a Pythagoras theorem,
(AC)² + (AB)² = (BC)²
or, (AC)² = (BC)²- (AB)²
or, (AC)² = (10√3)² - (20)²
or, AC =
or, AC = 22.36 km
So, distance bearing of Marcus from Elouise is 22.36 km.

Step-by-step explanation:
f(-7) = 5(-7) - 3 = -35 - 3 = -38
Answer:
It Dropped -10 degrees.
Step-by-step explanation:
If the Temperature was -2 per hour for 5 hours it would make -10 degrees through that time period.
The formula is n/2(a1+an). n is the number of terms. a1 is the first value in the sequence and an is the value of the sequence at the nth term
