1 mile= 5280 ff
3 ft= 1yd
1 mile= 1760 yds
7 x 1760= 12320 yds
12320+880=13200 yds in the trail
hope this helps
Answer:
20
Step-by-step explanation:
10 percent = 2 (for this problem anyways)
So the remaining amount is 8, which leaves us with 12.
-10=10(k-9)
so,
-10=10k-90
that is just expanding the brackets by multiplying to k and-9
then.
-10=10k-90
move the-90 over by adding 90
so, 80=10k
k =80/10
k=8
Given a fragpole which makes a right angle with the point of observation with the angle of elevation as 50°.
Let x be the height of the flagpole, then

Therefore, the <span>equation that could be used to find the height of the flagpole is
</span><span>x/5 = sin 50</span>
Answer:
40
Step-by-step explanation:
Angles ABO, BAO, and AOB are the angles of isosceles triangle AOB. The angles at A and B are equal, so we have ...
AOB +2ABO = 180° . . . . . sum of angles in the triangle
100° +2ABO = 180° . . . . . . use the given value
50° +ABO = 90° . . . . . . . . divide by 2; next, subtract 50°
∠ABO = 40°
