Answer:
Angle A = 54
Angles on a straight line add up to 180.
So:
126 + a = 180
Rearrange for a.
a = 54
The answer will be :
53/200=2,5=250%
the side x is 15
bottom right angle is 31.61 degrees
other angle is 58.39 degrees
Here's the equation for direct variation. k=y/x [ f(x)=y]
Find k
k= 48/8=6
6=y/2
y=12
Hope this helps.
