Answer:
16. Angle C is approximately 13.0 degrees.
17. The length of segment BC is approximately 45.0.
18. Angle B is approximately 26.0 degrees.
15. The length of segment DF "e" is approximately 12.9.
Step-by-step explanation:
<h3>16</h3>
By the law of sine, the sine of interior angles of a triangle are proportional to the length of the side opposite to that angle.
For triangle ABC:
- ,
- The opposite side of angle A ,
- The angle C is to be found, and
- The length of the side opposite to angle C .
.
.
.
Note that the inverse sine function here is also known as arcsin.
<h3>17</h3>
By the law of cosine,
,
where
- , , and are the lengths of sides of triangle ABC, and
- is the cosine of angle C.
For triangle ABC:
- ,
- ,
- The length of (segment BC) is to be found, and
- The cosine of angle A is .
Therefore, replace C in the equation with A, and the law of cosine will become:
.
.

For triangle ABC:
- ,
- ,
- , and
- Angle B is to be found.
Start by finding the cosine of angle B. Apply the law of cosine.

For triangle DEF:
- The length of segment DF is to be found,
- The length of segment EF is 9,
- The sine of angle E is , and
- The sine of angle D is .
Apply the law of sine:
.
Answer: 875.5x
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
Write an expression:
x + 1 = 1.011
solve the expression:
subtract 1 on left n right of the = sign
x + 1 - 1 = 1.011 - 1
x = 0.011
Round to nearest hundredth
x = 0.01
The solution is solving an algebra equation with the ans rounded to the hundredth.
Answer:
Step-by-step explanation:
Given
See attachment for complete question
Required
Identify the unexplored point
Since the shaded region has been explored, an unexplored point will be located in the white region.
The given points are:
Plot each of the above points on the grid (See attachment 2)
In attachment 2, only (4,3) lies on the white region.
<em>Hence, (4,3) has not been explored</em>
