Answer:
angle 1 and angle 3 are congruent
Step-by-step explanation:
Angles supplementary to the same angle are congruent. Here both angles 1 and 3 are supplementary to angle 2, so angles 1 and 3 are congruent.
_____
If you like, you can get there algebraically:
m∠1 + m∠2 = 180
m∠3 + m∠2 = 180
Subtract the second equation from the first:
(m∠1 + m∠2) - (m∠3 + m∠2) = (180) - (180)
m∠1 -m∠3 = 0 . . . . simplify
m∠1 = m∠3 . . . . . . add m∠3
When angle measures are the same, the angles are congruent.
∠1 ≅ ∠3
I have a good record of guessing the right one so I would say #1.
Answer:
36 centimeters squared.
Step-by-step explanation:
Use the formula for the area of a square.
Let's see
Total votes be x
- 45% of x=3600
- 0.45x=3600
- x=3600/0.45
- x=8000
Now total percentage of vote
Not voted=4%
Find not voted
Total voted
