Ok jet the inverse is jut the function backwards,like a reciprocal.
So it should be D. (83,47)
Hope I could help you
Answer:
x =4
Step-by-step explanation:
sum of angles in a triangle = 180
(equilateral triangle) all sides are equal
180 ÷ 3 = 60
10x+20 =60
10x = 60 - 20
10x = 40
10x ÷10 = 40÷ 10
x = 4
Since the triangles make up a spinner, the triangles are isosceles.
The base is 2 cm and the perimeter is 10 cm.
The measure of the two legs can be determined from
2 + 2x = 10
Where is the length of the leg
Solving for x
x = 4
The area an isosceles is calculated using

where b is the length of the base
Substitute the values and multiply with the number of triangles in the spinner
60u=15 litres
1u=15l÷60
=0.25l
40u=0.25l×40u
=10l
Ans:10 litres of paint thinner
