You must use trig for this. If you are using a calculator make use it is first set in degrees!! To find C, you can use cosine, which is adjacent over hypotenuse. 
You must use inverse cosine since the sides are given, not the angles. 
cos∧-1(120/122)
You have inverse cosine which is cosine negative one and multiply it by adjacent over hypotenuse sides.
The answer is 10.3888 degrees.

Answer:

hope this helps

Step-by-step explanation:

so first you would convert the 3 3/8 to a improper fraction which would be 27/8 the n you would multiply the 27 by 2 and the 8 by 1 then 27  and you would get 64/8 and 8 divided by 64 is 8 so the volume is 8

the dashes are fractions.

The hypotenuse of a right triangle is 7 inches, and one of the legs is the square root of thirteen inches. Find the length of th
defon
By using the well-known Pythagorian theorem we can write this equation:
7^2=13+b^2 -> b^2=49-13=36
The square root of 36 is obviously 6.
So, the other leg has a length of 6 inches :)

A line passes through the point (6,-3) and has a slope of -3/2 write an equation in slope intercept form
Vadim26 [7]

Answer:

y = - \frac{3}{2} x + 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - \frac{3}{2}, hence

y = - \frac{3}{2} x + c ← is the partial equation

to find c substitute (6, - 3 ) into the partial equation

- 3 = - 9 + c ⇒ c = - 3 + 9 = 6

y = - \frac{3}{2} x + 6 ← equation in slope- intercept form
