Answer:
n=37
Step-by-step explanation:
Two lines intersect and create vertical angles.
The vertical angles are
We know that vertical angles (also called vertically opposite angles) are equal. Therefore:
50
.
a) x=3
y= 4+4*3
=16
b) x=4
y= 4+4*4
= 20
c) x=7
y= 4+4*7
= 32
d) x=8
y= 4+4*8
= 36
Actually Welcome to the Concept of the areas.
Since we know that, radius = diameter /2
here, => d = 2r ,
hence we use the formula as,
A = πr^2 ,
here option d.) is correct.
