Answer:
distance = 1.5 miles(approx.)
Step-by-step explanation:
given,
speed of sound = 1130 ft/s
1 ft = 0.3048
1130 ft/s = 0.3048 × 1130 m/s
= 344.424 m/s
time = 7 second
distance = speed × time
distance = 344.424 × 7
distance = 2410.968 m
1 m = 0.0006214 miles
2410.968 m = (0.0006214 × 2410.968) miles
distance = 1.498 miles
distance = 1.5 miles(approx.)

Answer: SAS Similarity theorem.
Explanation.
SAS stands for Side - Angle - Side.
SAS theorem states that if two triangles have
corresponding angles that are congruent and corresponding sides
with identical ratios, then the triangles are similar.
And that is what the figure shows:
1) The angle at M is the same for both triangles.
2) The ratios of the sides are: 2/3 and 4 /6. Given that 2/3 = 4/6 you have that the two corresponding sides have identical ratios.
3. x+100 = 90 alternate interior angles are equal
subtract 100 from each side
x+100 - 100 = 90-100
x = -10
4. 17x+1 = 120 alternate exterior angles are equal
subtract 1 from each side
17x+ 1 -1 = 120 -1
17x = 119
divide each side by 17
17x/17 = 119
x =7
