Step-by-step explanation:
The secant- secant angle PRS is half the measure of the difference of the intercepted arcs, that is
(PD - QS) = 50 ( multiply both sides by 2 )
PD - QS = 100, that is
12x + 8 - (4x + 4) = 100
12x + 8 - 4x - 4 = 100
8x + 4 = 100 ( subtract 4 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
arc PD = 12(12) + 8 = 144 + 8 = 152°
arc QS = 4(12) + 4 = 48 + 4 = 52°
The total surface area of the cuboid is 120 cm2
That is an example of the use of the distributive property of multiplication. However, you wrote the problem incorrectly... the sign following 5 changed from ÷ to +
