Since angle 4 is across from angle 2 it is equal to it because they are called opposite or vertical angles which are always equal.

Angle 4 = 143 degrees.

Angles 1 and 2 are supplementary because they share one of the same lines. This means their angle values add up to 180 which is the angle measure of a line.

180 - 143 = 37

Angle 1 = 37 degrees.

Since angle 3 is across from angle 1 it is equal to it because they are called opposite or vertical angles which are always equal.

Angle 3 = 37 degrees.

I hope this helps!

The measure of angle 1 would be 37 degrees because a straight angle is 180 degrees.

You subtract 143 from 180 to get 37 degrees.

measure of angle 1 = 37


For the measure of angle 3, it is the same as the measure of angle 1 because vertical angles have the same angle measure. Angle 1 and Angle 3 are vertical angles.

measure of angle 3 = 37


Angle 4 and Angle 2 are vertical angles, so they have the same measure.

The measure of Angle 2 is given (143).

measure of angle 4 = 143

How many liter of 15% weed killer mixture must be added to 5 liters of 10% weedkiller mixture to make 12% weed killer mixture?
finlep [7]

Answer: 3 1/3 liter

Brainliest? <3

let x equal the number of liters of 15% weedkiller.

your equation is .15 * x + .10 * 5 = .12 * (x + 5)

simplify to get .15 * x + .10 * 5 = .12 * x + .12 * 5

simplify further to get .15 * x + .5 = .12 * x + .6

subtract .12 * x from both sides and subtract .5 from both sides and simplify to get .03 * x = .1

divide both sides by .03 to get x = .1 / .03 = 3.333333333 rounded to 9 decimal digits.

you would need 3.333333333 liters of 15% solution to be added to 5 liters of 10% solution to get 8.333333333 liters of 12% solution.

.15 * 3.333333333 = .5

.10 * 5 = .5

.5 + .5 = 1

5 + 3.333333333 = 8.333333333

1 divided by 8.333333333 = .12 which is equal to 12%.

To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos
abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be R(x)=. Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

R(x)=150+1.75x

The problem tells us that we are driving 96 miles, so we can plug in 96 for x and solve.

R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318

The total cost of the rental is going to $318.

Hope this helps!
