+37153 The two angles are equal 11(y-10 ) = 4y -5 solve for 'y' then pts = 11 ( y-10)
+208 Hey there,
Given the X rule (I don't know if this is what it is actually called), we know that the two given angles are equal to eachother so we can just use some rearranging to find what y is
11y-110=4y-5
7y=105
y=15
Thus PTS will be 11(15-10)=55 degrees
Hope this helped :)
