It's really simple
if a+95=180 you solve for a
a+95=180
-95 -95
a=85
a triangle in total is 180 degrees
now that you know two of the angles find x is really easy
you add 60+85
you get 145
you then subtract 180-145
and get 35 as the answer
x=35

Answer:
Step-by-step explanation:
Given
x ----- y
0.5. --- 0.8
1. --- 1.6
3.--- 4.8
25. --- 40
Required
Determine the constant of proportionality
This can be calculated using the following formula:
; Where r is the constant of proportionality;
Solve for r
When x = 0.5; y = 0.8
When x = 1; y =1.6
When x = 3; y = 4.8
When x = 25; y = 40
Notice that the value of r is constant throughout;
Hence:
