Answer:
The correct answer is 61.08 foot.
Step-by-step explanation:
Length of the string of the kite, Mr. Black is flying is 65 foot. Thus the length between the kite and Mr. Black is given by 65 foot.
Angle of elevation is 70°.
We need to calculate the height of the kite above Mr. Black's head. The height is given by finding the sine of the angle of elevation.
Let the height be x foot.
Thus sin 70° =
⇒ x = sin 70° × 65
⇒ x = 61.08
Thus the height of the kite above Mr. Black head is 61.08 foot.
Answer:
432
Step-by-step explanation:
The simplified version of this expression is -4x.
Work
1. 1x-7x-(-2x)
2. 1x-7x+2x
Now just combine the terms.
3. -6x+2x
4. -4x
The length of BC is equivalent to 12 units
<h3>Midpoint of a line</h3>
If the midpoint if Ac is B, then the expressions below are true;
AB+BC = AC
AB = BC
Given the following parameters
AB = x + 6, and
AC = 5x - 6
BC = x + 6
Substitute
x+6+x+6 = 5x - 6
2x+12 = 5x - 6
2x-5x = -6-12
-3x = -18
x = 6
Determine the measure of BC
BC = x + 6
BC= 6 + 6
BC = 12units
Hence the length of BC is equivalent to 12 units
