Answer:
62.7°
Step-by-step explanation:
Answer:
-3 times -2 is 6 not -6
Step-by-step explanation:
Thats where he messed up
X = 47°
y = 90°
These are the angles, comment if you would like to know the explanation but these are the answers
$187.52 is 6.24% off of 200 and the amount saved is $12.48. If this is not what you meant let me know. The math is $200 × (1 - 6.24) = $187.52. Hope this helps!
The <em><u>correct answers</u></em> are:
Supplementary; ∠2 and ∠3; substitution; 2.
Explanation:
Supplementary angles are angles whose measures sum to 180°. Thus this is the first answer.
Since we are told that ∠2 and ∠3 are supplementary, their measures sum to 180° and they are the second answer.
We know that m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°. We can substitute "m∠2 + m∠3" for 180° in the first equation; this is the substitution property.
To isolate m∠1 on the right, we will subtract m∠2 from each side, and get that m∠1 = m∠3 and the angles are congruent.
