Answer:
m∠3 = 73°
Step-by-step explanation:
Vertical angles are equivalent in measure. Complement angles add up to 90°, so subtract 17° from 90° to get your answer.
Answer:
(x-1)(x-9)
Step-by-step explanation:
7x - 1 + 6x - 1 = 180
add the x’s, add the numbers
13x - 2 = 180
add 2 to 180
13x = 182
divide 182 by 13
x = 14
Answer:
Step-by-step explanation:
The starting equation is
12-(3x+13)=0
First add 3x+13 to both sides so that only 12 is on the left
12=3x+13
now subtract 13 from both sides to isolate your variable
-1=3x
Finally divide both sides by 3 to get your final answer
x=-1/3
12 divided by -4 equals-3 .
