Answer:

41°

Step-by-step explanation:

The angle below (2x-5) is also 113° (which i hope you know why)

Then to find (2x-5)° you would subtract 180 - 113 to get the angle because both those angles would add up to 180° because it is a straight angle which gives you 67°

Then you need to find x by solving the equation 2x - 5 = 67 which would give you x = 36, so you would multiply that by 2 for the angle on the side which would be 72°

Then bc the angles on the inside of the triangle all add up to 180° as well, you would add 72 + 67 = 139, then do 180 - 139 giving you d° as 41°

Answer:

41º

Step-by-step explanation:

Because of parallel lines, (2x-5)º=180º-113º, so (2x-5)º=67º.

(2x-5)º=67º
2x-5=67º
2xº=72º
x=36º

The angle that says (2x)º will be (2[36])º=72º.

So the other angle will be 180-67-72=41º as the sum of a triangle's interior angles is 180º.

What is the equation of the line that passes through the point (-7, 2) and has a slope of -1?

lorasvet [3.4K]

Answer: y= -1x - 5

Step-by-step explanation:

The equation has to be in slope-intercept form which uses the formula

y=mx+b where m is the slope and b is the y-intercept.

So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.

the x coordinate is -7 and the y coordinate is 2

2 = -1(-7) + b

2 = 7 + b

-7 -7

b = -5 the y intercept is -5

Now the equation will be y= -1x - 5

Alice and Bob each have a certain amount of money. If Alice receives $n$ dollars from Bob, then she will have $4$ times as much

oksano4ka [1.4K]

Answer: 31 : 9

Step-by-step explanation:

Assume the following:

Alice's amount = P

Bob's amount = Q

Amount received = n

If Alice receives $n$ dollars from Bob ;then she will have $4$ times as much money as Bob.

P + n = 4(Q - n)

P + n = 4Q - 4n

P = 4Q - 4n - n

P = 4Q - 5n - - - - (1)

If, on the other hand, she gives $n$ dollars to Bob, then she will have $3$ times as much money as Bob

P - n = 3(Q + n)

P - n = 3Q + 3n

P = 3Q + 3n + n

P = 3Q + 4n - - - - - - (2)

Equating both equations - (1) and (2)

4Q - 5n = 3Q + 4n

4Q - 3Q = 4n + 5n

Q = 9n

Express P in terms of n, use either equation (1) or (2)

From equation 2:

P = 3Q + 4n

Substituting Q = 9n

P = 3(9n) + 4n

P = 27n + 4n

P = 31n

Alice's amount = P, Bob's = Q

Ratio = P:Q

Question: If the triangle is right, the hypotenuse is?? Plsss help

raketka [301]

Answer:

the hypotenuse of the given triangle is 48.5 ft

Step-by-step explanation:

the ways to detect the hypotenuse of a triangle are :

longest side of a right angled triangle is the hypotenuse of the triangle .
side opposite to the right angle ( 90° ) is the hypotenuse of the right angled triangle .

 in the given figure the longest side is 48.5, hence it's the hypotenuse....
