Step-by-step explanation:

To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.

We try out all the options:

39² = 1521, 15² + 36² = 1521.

12² = 144, 8² + 4² = 80.

17² = 289, 13² + 9² = 250.

Since 39² equals 15² + 36², option A is the correct answer.

We must find out 3 angles to make a right triangle.

The formula is c² = a² + b².

We know that the longest angle is equal to the other two angles.

Now, let's work this problem out.

Option A

39² = 1521

15² + 36² = 1521.

Option B

12² = 144

8² + 4² = 80.

Option C

17² = 289

13² + 9² = 250.

39² = 15² + 36², so the answer is A.

✔️ Hence, verified. ✔️

In each figure below find m ∠1 and m∠2, if a||b. Justify with<br> reasons your solution.
Mazyrski [523]

Answer:

m<1 = 130°

m<2 = 50°

Step-by-step explanation:

Since given that line a is parallel to line b, and <1 and 130° are interior angles that alternate each other, therefore:

m<1 = 130° (alternate interior angle theorem)

Also,

130° and <2 lie on same side inside the parallel lines cut across by the transversal, therefore,

m<2 + 130° = 180° (same side interior angles theorem)

m<2 = 180° - 130°

m<2 = 50°

The vertex of a parabola is at (8,-1)and its y-interpret is-17. Which function represents the parabola
Ilia_Sergeevich [38]

Answer:

D

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (8, - 1), thus

y = a(x - 8)² - 1

To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.

- 17 = a(0 - 8)² - 1

- 17 = 64a - 1 ( add 1 to both sides )

- 16 = 64a ( divide both sides by 64 )

a = \frac{-16}{64} = - \frac{1}{4}

y = - \frac{1}{4}(x - 8)² - 1 → D

Find the length of a rectangular lot with a perimeter of 120 meters if the length is 6 meters more than the width
Vladimir79 [104]

Answer:

The length is 33 and the Width is 27.

Step-by-step explanation:

So I made it easier by only looking at half of the rectangle. 120 divided by 2 is 60. So out of the length and width, it had to add to equal 60. I plugged in a few numbers and determined 27 and 33. SO, if you add those together it equals 60 while 33 is 6 more meters than 27 and two 27 and two 33 equals 120 for the whole rectangle
