In a right triangle, angle C measures 40. the hypotenuse of the triangle is 10 inches long. what is the approximate length of th
IrinaVladis [17]

Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.


               (The side adjacent to angle C ) divided by (hypotenuse)

is the cosine of angle C .       


                    (adjacent) / (10 inches)  =  cos(40 degrees)

Multiply each side by (10 inches):

                    Adjacent side = (10 inches) x cos(40) =

                                              (10 inches)  x  0.766  = 

                                                              7.66 inches   (rounded)

Ostrovityanka [42]
On her map 1 inch is equal to 20 miles. 

5x=100

divide both sides by 5 

x=20

5 is for the 5 inches.
x is for the unknown.
100 is the 100 miles between the cities. 

So the scale 1:20

Indicate in standard form the equation of the line passing through the given point and having the given slope.
Svetradugi [14.3K]
Equation of a line passing through point (x1, y1) with slope m is given by y - y1 = m(x - x1)
y - 2 = -1/2(x - 6)
2(y - 2) = -(x - 6)
2y - 4 = -x + 6
x + 2y = 6 + 4
x + 2y = 10

R - 9S = 2 3R - 3S = -10
GrogVix [38]
R-9s=2  add 9s to both sides

r=2+9s  making 3r-3s=-10 become:

3(2+9s)-3s=-10  perform indicated multiplication on left side

6+27s-3s=-10  combine like terms on left side

6+24s=-10  subtract 6 from both sides

24s=-16  divide both sides by 24

s=-16/24

s=-2/3, making r-9s=2 become:

r-9(-2/3)=2  perform indicated multiplication on left side

r+6=2 subtract 6 from both sides

r=-4

So s= -2/3 and r= -4
