The equations that can be used to the value of x are 1) x+90+(x-10)=180 and 2) x+90+(2x+40)=180.
<u>Step-by-step explanation:</u>
Two properties can be used to find the value of the x.
1) Sum of Interior angles of a triangle is 180°.
⇒x+90°+(x-10)°=180.
2x+80°=180°.
2x=180°-80°.
2x=100°.
x=50°.
⇒(x-10)°=40°.
2) The Angle of the straight line is 180°.
From the given diagram, BC is a straight line ray with C as intersecting point. this will result in two angles. (refer the diagram).
The sum of those two angles will be 180°.
⇒ (x-10)°+ (2x+40)°=180°.
(3x+30)°=180°.
3x=150°.
x=50°.
∴(x-10)°=40° and (2x+40)° = 140°.
∴The equations that can be used to the value of x are x+90+(x-10)=180 and x+90+(2x+40)=180.
Answer:
Step-by-step explanation:
The relation R is x = y/2 and values of x and y must be in the set A. That is they must be 1 , 2 or 4 and satisfy the relation x = y/2.
So the ordered pairs in this relation are (1, 2) and (2, 4) . Note that 4 cannot be x as that would make y = 8 which is not a member of Set A.
I hope this helps.

You have to get the IQR to get the answer
Answer:
1023
Step-by-step explanation:
Positive numbers are numbers that are greater than 0.
As maximum value of numbers x and y is 4,
....(i)
So,
So, maximum value of the product is 1024.
Also, its given that sum of numbers x and y is 5, so ...(ii)
On using equations (i) and (ii), we get
So,
Therefore, minimum value of the product is 1.
Difference between the maximum and minimum value of the product = maximum value of the product - minimum value of the product
=1024 - 1 = 1023
You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________
The equation is n + 16 = 9
On the left side, you subtract 16 from (n + 16) and you have 'n'.
On the right side, you subtract 16 from 9 and you have -7 .
Now the equation says n = -7
