Answer:

The answer here would be D.

Step-by-step explanation:

When looking at the angle you can see that it is a straight line with a intersecting line. This tells you that you will have supplementary angles, or angles that add up to 180 degrees.

You can only have supplementary angles when they are on either side of a straight line that has been intersected.

Since supplementary angles have to add up to 180 degrees, and you already know that one part of the current supplementary angles is 50 degrees, you can do the math,

180-50=130

To get your answer of D. 130

If the length of a rectangle is 5 m more than its width find the values of length and width if the area of a rectangle is 500 m²

astra-53 [7]

Answer:

Length of the rectangle =25

width of the rectangle = 20

Step-by-step explanation:

Step(i):-

Let 'x' be the width of the rectangle

Given that the length of a rectangle is 5 m more than its width

Given that Area of the rectangle = 500m²

length of a rectangle = x +5

width of a rectangle = x

Step(ii):-

Area of the rectangle = length × width

500 = x ( x+5)

x² + 5 x = 500

⇒ x² + 5 x - 500 =0

⇒ x² +25x - 20 x - 500 =0

⇒ x( x+25) -20(x+25) =0

⇒ (x-20)(x+25) =0

⇒ x =20 and x=-25

we can choose x =20

Step(iii):-

Length of the rectangle = x +5 = 20 +5 =25

width of the rectangle = 20

Final answer:-

Length of the rectangle =25

width of the rectangle = 20

Find the three cube roots of z=−3+3i in trigonometric form. Please show your work :) ill give brainliest

disa [49]

Answer:

The Answer to your problem is 3 √ 2

Step-by-step explanation:

Step 1. Find 0 ( helps to plot z on complex plane)

z is in quadrant 4

0 is between - $\pi$ /z and 0

Step 2. Find modulus |z|

|z|= check mark 3 to the power of 2 + (-3) power of 2 = check mark, 9+9 = check mark 18 =check mark 9.

Step 3. Write out z in polar form

z = 3 check mark 2.

What is the length of the longer of the two chords shown?

Rainbow [258]

Answer:

Step-by-step explanation:

When 2 chords intersect then the product of the parts of one chord equal the product of the parts of the other chord, that is

12(x - 7) = 4(x + 3) ← distribute parenthesis on both sides

12x - 84 = 4x + 12 ( subtract 4x from both sides )_

8x - 84 = 12 ( add 84 to both sides )

8x = 96 ( divide both sides by 8 )

x = 12

Thus

12 + x - 7 = 12 + 12 - 7 = 17

4 + x + 3 = 4 + 12 + 3 = 19 ← longer chord
