38 degrees.
EXPLANATION
There are 2 angles.
The angles must add up to 180.
So taking 180 and subtracting the already known angle, of 142.
Will get us with 38.
We can check the work by doing 38 + 142.
Hope this helps! have a gud day
Find f (3) when f (x) =2x is the same as finding u when x= 3 ,for y=2x
to evaluate a function substitute the input (the given number or expression ) for the functions variable(place holder x). Replace the x with the number or expression
Answer:
No solution
Step-by-step explanation:
from the second equation x = -8 + 2y
By substituting in the first equation 4(-8 + 2y) -8y = -16
-32 +8y -8y = -16
-32 = -16
the left hand side not equal the write and side
So there is no solution for the system of equations
means the two lines are parallel
Answer:
18 1/2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since the triangle has a right angle, we are going to use pythaogoran theoem, which is 
, where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.
9+36=c^2
45=c^2
=
Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical
The perfect square root is 9 because 9 goes into 45 5 times.
Then take the sqr root of 9 and we have
