15 POINTS: The ratio of the same side interior angles of two parallel lines is 33:3. Find the measures of all eight angles forme

larisa [96]

Answer:

$15^\circ,165^\circ,15^\circ,165^\circ\\15^\circ,165^\circ,15^\circ,165^\circ$

Step-by-step explanation:

The ratio of the same side interior angles of two parallel lines is 33:3

If two parallel lines are cut by a transversal

Sum of the same side interior angles = 180 degrees.

Therefore, the two same-side interior angles are:

$\dfrac{33}{36}\times 180^\circ =165^\circ\\\dfrac{3}{36}\times 180^\circ =15^\circ$

We can then say that the measure of all eight angles formed by the parallel lines and transversal starting from the upper left in a clockwise rotation is:

$15^\circ,165^\circ,15^\circ,165^\circ, 15^\circ,165^\circ,15^\circ,165^\circ$

What is equivalent to 3 radical 8

klemol [59]

Answer:

Equivalent $3\sqrt{8}=6\sqrt{2}$

Step-by-step explanation:

Given: 3 radical 8

Mathematically 3 radical 8 can be written as $3\sqrt{8}$

We have to find an equivalent to $3\sqrt{8}$ .

Given expression can be written as ,

$3\sqrt{8}=3\sqrt{4 \times 2}$

On further simplification, we get,

$3\sqrt{4 \times 2}=3(\sqrt{4} \sqrt{2} )$

We know $\sqrt{4}=2$

further simplification gives,

$3\sqrt{8}=6\sqrt{2}$

Thus, Equivalent $3\sqrt{8}=6\sqrt{2}$

The sum of three numbers is 24. Twice the middle number is 2 more than the largest number, and the largest number is equal to th

harina [27]

Answer:

x = 5, y = 7, z = 12

Step-by-step explanation:

Let the numbers be x, y and z

x + y + z = 24
2y = z + 2
z = x + y

Solving by substitution:

x + y + z = z + z = 24
2z = 24
z = 12

2y = z + 2
2y = 12 + 2
2y = 14
y = 7

z = x + y
x = z - y
x = 12 - 7 = 5

The answer:

x = 5, y = 7, z = 12
