Suppose that both planets are spherical. radius of Saturn =142984/2=71,492
Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10
Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10
Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km

Since BD bisects angle ABC, that means angle ABD and angle CBD are equal to each other. With that set up the equation to solve for x like this:
-4x+33 = 2x+81
-2x -2x
————————
-6x +33 = 81
-33 -33
————————
-6x = 48
————- (divide by -6)
-6
x = -8
Now substitute that to ABD
-4(-8) +33
32 +33
=65
here’s CBD
2(-8) + 81
-16 + 81
=65
Finally angle ABC will be double the amount of ABD or CBD so 65 times 2 is 130.
ANSWERS: (angles)
ABD and CBD: 65
ABC: 130
YZ = 16. The triangles are congruent. This would be AAS so YZ = 16 because of CPCTC.
Answer:
-5.6666.... is a rational number and 3.25 is a rational number but not integer too. the rest you got all right, good job.
hope that answers your question
dont hesitate to comment if you need some explanation about this topic
