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.
First try it out yourself then compare answers. Remember, all squares have the same length per each side.
a) 3025
b) 25300
Answer:
Step-by-step explanation:
Let's write a equation.
5 ft = 20 seconds
(five feet is reachable in 20 seconds)
Divide both sides by 5.
5/5=1
20/5=4
1 ft = 4 seconds
Let's say the destination is d and f is foot.
d = 4f
