+13 A) find the value of X
B)is the triangle equilateral, isosceles or scalene? Explain 
+37146 Angle Q = 3x degrees due to inscribed angle
P = 5x+5 " " " "
R = 4x-5
Added together they equal 180 degrees 3x + 5x+5 + 4x-5 = 180 12x= 180 x= 15 degrees
Q= 45 degrees P = 80 degrees R= 55 degrees so it is a scalene triangle

+56 Sorry for not perfect english, but i am pretty sure that you can understand.
The rule is, here, circle equals 360 degrees.
(QR)+(QP)+(PR) = Circle
(QR)+(QP)+(PR) =360 degree
(QR)+(QP)+(PR) =(10x+10)+(8x-10)+(6x)
24x=360
x=15
