B = 58.7°

b = 15.9 ft

a = 9.7 ft

Step-by-step explanation:

We are given;

C = 90°

A = 31.3°

c = 18.6 ft

Since sun of angles in a triangle is 180°, thus; B = 180 - (90 + 31.3)

B = 58.7°

From law of sines, we can find b.

Thus; b/sin B = c/sin C

b/sin 58.7 = 18.6/sin 90

b/0.8545 = 18.6/1

b = 18.6 × 0.8545

b = 15.8937 ft

To the nearest tenth gives;

b = 15.9 ft

Similarly;

a/sin A = c/Sin C

a/sin 31.3 = 18.6/sin 90

a/0.5195 = 18.6

a = 18.6 × 0.5195

a = 9.6627

To the nearest tenth gives;

a = 9.7 ft

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
