Total for all triangles=180
Step-by-step explanation:
In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:
3y+2y+y=180
6y=180
y=30
It's fairly easy to solve from there. Just more multiplying and subtracting.
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
Answer:

Explanation:
-40 - 6m + 1 = - 2
- Simplify Both Sides Of The Equation
−40 − 6m + 1 = −2
−40 + −6m + 1 = −2
(−6m) + (−40 + 1) = −2 (Combine Like Terms)
−6m + −39 = −2
= −6m − 39 = −2
−6m − 39 + 39 = −2 + 39
−6m = 37
-6m / -6 = 37 / -6

Looks like the labeled angle is bisected, in which case we can apply the angle bisector theorem. For this triangle, it says

Solve for
:




Then either
or
, but since
is a length, it must be positive. So <em>x</em> = 2.
