Answer:
x = 18 ; y = 10 ; z = 102°
Step-by-step explanation:
The triangle in the pic is an isosceles triangle.
As it is an isosceles triangle , it's two sides will be equal .



Also, both the base angles will be equal.



According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,



Well, you have the radius and the center already. So all you have to do is graph the center point, then count from that center point out 5 units, then draw the circle.
13x-91=12
+91=+91
__________
13x = 103
___. ___
13. 13
X= 7.92 or 7.9
Answer: (0,-5), (5, 0), (10, 5) and (15,10).
Step-by-step explanation:
Given equation: 
To find its inverse we will find the value of x .
Subtract 5 from both sides

Switch y to x, we get
y= x-5, which is the inverse function.
At x=0,
y=-5
At x= 5,
y=0
At x= 10 ,
y=5
At x= 15,
y= 10
Hence, the four points contained in the inverse: (0,-5), (5, 0), (10, 5) and (15,10).
There are 12 months in a year which will be equal to 285 times 12 = $3420
after 2 years (24 months)... 285 times 24 = $6840
after 5 years (60 months).... 285 times 60 = $17, 100
