Q: If the 3 inner angles of a triangle are congruent, what is the measure of each one?
A: Exterior Angle The measure of an exterior angle of a triangle is equal to the sum of the mesures of the two non-adjacent interior angles. Hope it helped please mark me brainliest/
X is equal to -0.4, good luck!
Because BD is the angle bisector, and m∠ABC=40, m∠ABD is 20.
In case you'll need to find out x and y:
3x-1=34-2x, and 3y+6=5y-18
solve: 5x=35, x=7
2y=24, y=12
(m∠ABD=3x-1=3*7-1=20, again, the answer is in this case)

The moons A, B, C form a right triangle with AC forming a hypotenuse with the diameter of the planet and the distance of both moons from the surface. So add A to the surface, plus the diameter of the planet, plus surface to c.
115000+45000+115000 = 275000
