In the figure, j∥k and m∠2 = 117°. What is the m∠3? Enter your answer in the box. ° Line t diagonally crossing parallel lines j and k (reading from top to bottom). Angles formed by t crossing j are labeled one through four, starting at top right and going counterclockwise, where angle one is acute. Angles formed by t crossing k are labeled five through eight, starting at top right and going counterclockwise.

Answers

Answer:

63 degrees

Step-by-step explanation:

Since the angles are going counter-clockwise, angle 2 and angle 3 are supplementary, meaning that they add up to 180 degrees.

Since angle 2 is 117 degrees, 180 - 117 = 63. Therefore, angle 3 is 63 degrees

It costs $15 for one surfing lesson and $25 per day to rent a surfboard. Write an expression for the total cost of one lesson and renting a surfboard for y days.

Answers

Answer:

15 + (25*y). y is the amount of days.

The expression for the total cost of one surfing lesson and renting a surfboard for y days is 15 + 25y

What is Expression?

An expression is combination of variables, numbers and operators.

The total cost of one surfing lesson and renting a surfboard for y days can be expressed as:

Total cost = Cost of surfing lesson + Cost of surfboard rental for y days

The cost of one surfing lesson is 15, so we can substitute that into the expression:

Total cost = 15 + Cost of surfboard rental for y days

The cost of surfboard rental for y days is 25 per day, so the total cost for y days can be expressed as:

Cost of surfboard rental for y days = 25 y

Substituting this into the original expression, we get:

Total cost = 15 + 25y

Therefore, the expression for the total cost of one surfing lesson and renting a surfboard for y days is 15 + 25y

A right triangle has a leg length of 10 meters and a hypotenuse that is 26 meters. What is the length of the other leg?

Answers

Answer:

The length of the other leg is 24 meters.

Step-by-step explanation:

Well, let's think about the equation that gives us the hypotenuse in the first place, the Pythagorean theorem (which only works on right triangles!).

[tex]a^2+b^2=c^2[/tex]

The a^2 is one side of the triangle that we know and the b^2 is the other, the c^2 is the hypotenuse we are trying to solve.

Seeing that in this question, we can put 10, in the place of a^2, and 26 in the place of c^2

[tex]10^2+b^2=26^2[/tex]

That's what we have down the information we have, but now we'll have to do some rearranging to solve for the other leg's length. First let's square the numbers, 10^2 = 100 and 26^2= 676!

[tex]100+b^2=676[/tex]

Now we need to get b^2 by itself so we can solve it! Let's subtract 100 from both sides to do so,

[tex]100-100+b^2=676-100[/tex]

[tex]b^2=676-100[/tex]

[tex]b^2=576[/tex]

Now we got b^2 = 576!

But that's not our answer we have to square root it to get rid of the squared part!

[tex]\sqrt{b^2} = \sqrt{576}[/tex]

and when we do that we get,

[tex]b=24[/tex]

The length of the other leg is 24 meters!

The length of the other leg is 24 m.

What is the Pythagorean theorem?

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

A right triangle has a leg length of 10 meters and a hypotenuse that is

26 meters.

The length of the other leg = x

We will apply the Pythagorean theorem.

x² + 10² = 26²

x² + 100 = 676

x² = 676 - 100

x² = 576

x = 24

Thus,

The length of the other leg is 24 m.
