1. If p || q. m∠2 = (10x+2)°, and m∠7 = (14x-50)°, find the angle measure.


Solve for m∠1, m∠2, m∠3, m∠4, m∠5, m∠6, m∠7, m∠8.

Answers

The picture includes solving for x and the angle measurement for all. Since angle 2 and 7 are equal you able to set those equations equal to each other to solve for x. Then plug the x value in to find the exact amount for the angle. Next you subtract that value from 180 to find the other value of angles.

If line m || line n and Ð2 measures 35°, what is the measure of Ð5?

Answers

Answer:

145

Step-by-step explanation:

angle 2 = angle 3

=>          angle 3 = 35

now, we have

=>         35+angle 5 = 180

=>         angle 5 = 180 - 35

=>         angle 5  = 145

Answer:

145°

Step-by-step explanation:

line m || line (Given)

[tex]m\angle 2 = 35\degree ......(1)[/tex] (Given)

[tex]m\angle 3 = m\angle 2 ......(2)[/tex] (vertical angles)

From equations (1) and (2)

[tex]\implies m\angle 3 = 35\degree[/tex]

[tex]m\angle 3 +m\angle 5 = 180\degree[/tex] (interior angles on the same side of transversal)

[tex] \implies 35\degree +m\angle 5 = 180\degree[/tex]

[tex] \implies m\angle 5 = 180\degree-35\degree[/tex]

[tex] \implies m\angle 5 = 145\degree[/tex]

alan would take 5 hours to build the wall of a house, and gavin would take 7 hours to build it alone. when they work together, they talk a lot, and their combined output decreases by 26 bricks per hour. working together, they build the wall in 4 hours. how many bricks are in the wall?

Answers

Answer:

96 bricks

Step-by-step explanation:

Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour

Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.

rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)

To clarify, x=the normal rate

4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)

4(x-26)=[tex]2 \frac{11}{12}[/tex]x

You flip a coin and roll a dice. The resultant outcome table where H means heads, T means Tails, and the number represents what number was rolled on the dice. The outcome list is as follows
What is the probability that the coin reads heads or tails and the dices number is less than or equal to 6?

Answers

Answer:

hee-hee

Step-by-step explanation:

We first have to find out how many possible outcomes are in total.

There are 2 outcomes for the coin, either that the coin reads heads or tails.

There are 6 outcomes for the die, from 1 to 6.

2 x 6 = 12

There are 12 possible outcomes.

Now let's move on to the favorable outcomes.

We want to get the coin to flip on either heads or tails, and that the die has a number greater than or equal to 6.

The coin can only flip heads or tails.

The die's sides only goes up to 6.

The probability that the coin reads head and tails and that the dices  number is less than or equal to 6 is 12/12 or 1. It is certain.

D. $10,535

Answers

Answer:

19,565

Step-by-step explanation:

35% of 30,100=10,535

subtract that by 30100

30100-10535=19565

quick mafss

Answer:

c

Step-by-step explanation:

original price=30100

35% off = 30100 * 35% = 30100 * 0.35 = 10535

10535 is the savings, so substract this from the original price to get new price

30100-10535= [19565]
