Answer:
x = 143°
Step-by-step explanation:
When chords cross, the angle between them is the average of the measures of the intercepted arcs. Here, it is useful to consider the larger angle where the chords cross, the supplement of 37°, which is 143°. That is the average of the two arc measures (x+5) and (x-5). That average is ...
((x +5) +(x -5))/2 = 2x/2 = x
In short, x = 143°.

Answer:
96 mph
step by step explanation:
240/2.5
Answer:
2232.48 meters
Step-by-step explanation:
From the diagram:
Radius of semicircle = 74
Length of straightway on each side = 1000
The length of school track:
Straightway on each side = 2 * 1000 m = 2000m
Length of semicircle = πr/2
Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785
Total Length = ( 2000 + 232.47785) = 2232.48 meters
Hope this helps!
