Someone

provide reasons for the statements.
given: ∠1 and ∠3 are vertical angles.
prove: ∠1 ≅ ∠3 .

statement reason
1. ∠1 and ∠3 are vertical angles : given

2. ∠1 and ∠2 form a linear pair.
∠2 and ∠3 form a linear pair.: definition of linear pair

3. ∠1 and ∠2 are supplementary.
∠2 and ∠3 are supplementary. :

4. m∠1 + m∠2 = 180˚
m∠2 + m∠3 = 180˚ :

5. m∠1 + m∠2 = m∠2 + m∠3:

6. m∠1 = m∠3 :

7. ∠1 ≅ ∠3 :

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

45

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
