Answer:
x = 80, y = 122
Step-by-step explanation:
I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).
3/4x+2/5x-2=90°,
23/20x - 2=90°,
23/20x = 92°,
92/(23/20)
20/(1/4)
20(4)
= 80.
Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.
180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122
Answer:
B.

16.
1/2= 0.5 and it takes 16 months to get to 8 inches.
0.5x16=8

Answer:
The first ship has the same speed as Saige's ship while the second and third do not have the same speed.
Step-by-step explanation:
d = Distance traveled by Saige's spaceship = 588 km
t = Time taken = 60 seconds
Speed is given by

The other ships



So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.
