Given

m∠1 = 62°

lines t and l intersect

Prove: m∠4 = 62°

To proof

Angle addition property

Two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles.

As shown in the diagram

m ∠1 + m∠ 2 = 180 °

( by linear pair property )

Given:

m∠1 = 62°

Put in the above equation

we get

m∠ 2 = 180° -62°

m ∠2= 118°

Also

m∠ 2 + m∠4 = 180°

( By linear pair property )

m∠4 = 180° - 118°

m ∠4 = 62°

Hence proved

A bag contains 10 blue, 6 green, and 4 red marbles. You choose a marble with one hand and then a second marble with the other ha
Sergeu [11.5K]

Answer:

6/95.

Step-by-step explanation:

Prob(red marble on the first choice) =  4/(10+6+4)

= 4/20

= 1/5.

Prob(green marble on the second draw) = 6/19.

Prob( read then a green)

= 1/5 * 6/19

= 6/95.

Christopher scored 7 more than two times the questions Mathew scored on the math test. If Christopher scored 87 on the math test
viktelen [127]

Answer:

40

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).
