raketka [301]3 years ago
4 0

Answer:

k = 32/ cos 64

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj side / hypotenuse

cos 64 =  32/k

k cos 64 = 32

k = 32/ cos 64

Answer:

13

Step-by-step explanation:

We know that a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 = c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 =c

The equation of a line is -2x6y=-18. find the slope and the y-intercept. Then use them to graph the line.
Vaselesa [24]

Answer:

Slope=\frac{1}{3} and Y intercept=-3

Step-by-step explanation:

-2x + 6y = -18

Simplifying the equation,

6y = 2x - 18

y=\frac{x}{3}-3

A general line can be written as,

y=mx + c

, m= Slope of the line

c=y intercept of the line

Y intercept is basically the point where the line intersects,  the y axis or the line x=0.

Therefore, from the above data m=\frac{1}{3}

and Y intercept= -3.

Subtract: 2/3 - 3/8 <br><br> answer in reduced terms
yaroslaw [1]

The answer would be 7/24

You can start by finding a common denominator. Since the lowest common denominator 3 and 8 have in common is 24 then that would be your denominator.

Then you can cross multiply 3*3= 9 and 2*8=16

\frac{16-9}{24}

16-9= 7

7/24

Then you are left with your answer:

\frac{7}{24} is already in reduced terms.

Hope this helps! :3
