Answer/Step-by-step explanation:
✔️Find k:
Reference angle = 60°
Hypotenuse = k
Opposite = 9
Therefore, using trigonometric ratio, we have:

Multiply both sides by k

Divide both sides by sin(60)




Rationalize



✔️Find f:
Reference angle = 60°
Opposite = 9
Adjacent = f
Therefore, using trigonometric ratio, we have:

Multiply both sides by f

Divide both sides by tan(60)


Rationalize



Answer:
b
Step-by-step explanation:
Answer:
55.5 kg.
Step-by-step explanation:
Potential energy = mgh
= m * 9.81 * 4.5 = 2450 where m is the mass of the man.
m = 2450 / (9.81* 4.5)
= 55.5 kg.
Answer:
12
Step-by-step explanation:
We know that 1/3 of a pizza is cheese meaning that 6 pizzas are made of cheese and there are only two leaving the rest pepperoni and 12 are left if we subtract the cheese pizzas minus the 18 pizzas we have 12 which are pepperoni.
The graph is showing the equation of circle x²+y²=4
<h3>What is a circle?</h3>
A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.
The given graph in the question represents the equation of the circle cutting the points on the x-axis and y-axis at 4 which is the radius of the circle.
The equation will be as follows:-
x²+y²=4
Hence the graph is showing the equation of circle x²+y²=4
