Answer:
3
Step-by-step explanation:
6x - 2w + 9 - 8 = 6x - 2w +1
= 6*2 - 2*5 + 1
= 12 - 10 +1
= 2 + 1 =3
Answer:
r = 13
Step-by-step explanation:
these angles are vertical and are congruent
8r + 6 = 9r - 7
6 = r - 7
13 = r
Answer:
18 5/12 is the answer.
Step-by-step explanation:
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180°. So from the figure, we can see that

Collecting all similar terms, we get

or

So the angle measures are now as follows:
