find the measure of all of the angles on the diagram​

Answers

Answer:

Angle 1: 135*

Angle 2: 45*

Angle 3: 45*

Angle 4: 135*

Angle 5: 135*

Angle 6: 45*

Angle 7: 45*

Angle 8: 135*

Step-by-step explanation:

So we have angle 2, 45*, we can subtract 45 from 180 to get the angle for 1. Since everything is the same size as either 1 or 2 we can just plug in the bigger angle number we have for it, ex 4= 135 and so is 7.

If you don't understand something please don't hesitate to ask.

Answer:

Step-by-step explanation:

∠2 = 45

∠3 = ∠2    {Vertically opposite angles}

∠3 = 45

∠7 = ∠3    {Corresponding angles}

∠7 = ∠45

∠6 = ∠7        {Vertically opposite angles}

∠6 = 45

∠1 + ∠2 = 180   {Linear pair}

∠1 + 45 = 180

∠1  = 180 -45

∠1 = 135

∠4 =∠1  {Vertically opposite angles}

∠4 = 135

∠8 = ∠4  {Corresponding angles}

∠8 = 145

∠5 = ∠4         {Alternate interior angles}

∠5 = 145

Answers

Answer:

There denominators are same, ie = 12

Step-by-step explanation:

Sum , 1 + 5/12 = (12 + 5) / 12

x=a+b+4 and a is inversely proportional to y²; b is inverseley propotional to 1/y. when y = 2 x = 18 and when y = 1 x = -3. find x when y = 4​

Answers

Answer:

When y = 4, x is equal to 39

Step-by-step explanation:

The given parameters are;

x = a + b + 4

a ∝ 1/y²

b ∝ 1/(1/y) = y

When y = 2, x = 18

When y = 1, x = -3

Therefore, we have;

a·y² = j

a = j/y²

b ∝ 1/(1/y)

∴ b ∝ y

b = k·y

When y = 2, x = 18, we have;

a = j/y² = j/2² = j/4

b = k·y = k·2

x = a + b + 4

∴ 18 = j/4 + k·2 + 4...(1)

When y = 1, x = -3, we have;

a = j/y² = j/1² = j

b = k·y = k·1 = k

x = a + b + 4

∴ -3 = j + k + 4...(2)

Making 'j', the subject of equation (1) and (2) gives;

From equation (1), we have;

18 = j/4 + k·2 + 4

∴ j = (18 - 4 - k·2) × 4 = 56 - 8·k

From equation (2), we have;

-3 = j + k + 4

∴ j = -3 - 4 - k = -7 - k

Equating the two values of 'j', gives;

56 - 8·k = -7 - k

56 + 7 = 8·k - k

63 = 7·k

k = 63/7 = 9

k = 9

From equation (2), we get;

-3 = j + k + 4

k = 9

∴ -3 = j + 9 + 4

j = -3 - 9 - 4 = -16

j = -16

When y = 4, we get;

x = a + b + 4

a = j/y²

b = k·y

∴ x = j/y² + k·y + 4

Plugging in the values of 'j', and 'k' and y = 4, gives;

x = (-16)/y² + 9·y + 4

∴ x = (-16)/4² + 9 × 4 + 4 = 39

x = 39

Therefore;

When y = 4, x = 39.

Who was it? Gemma sat in the moonlit shade beneath her favorite oak tree. Although she was past her curfew, she could not sleep. Not after the last dream. She could not remember anything from the dream, only the feeling of being lost and leaving everything behind. She buried her toes beneath the dirt and shuddered at the thought of the nightmare. Deciding that she was fretting over nothing, Gemma went back to the generously sized loft house that her mother and father had built before she was born. She smiled at the simplicity of it often. Morning came quickly, and Gemma quickly rose out of bed, remembering what day it was. She was a senior as of today, and could not miss her first day. After throwing a pair of khakis on and a loose feather shirt, she quickly wove her golden hair into separate braids and made her way out of the door. Her mother sat in the kitchen, laughing. The sight of her daughter running through the house like a crazed clown was the most hilarious thing she has seen all day. Sweetie, wait for me!, her mother shouted over the sound of the car door slamming. After they had arrived at Westbrooks Highschool, Gemma jumped out of the car and ran. Don't forget your lunch!, she heard her mother yell. Gemma turned around sharply, almost tripping, and ran back to grab her lunch. Her best friend, Amelia, spotted the golden-headed clown. She walked cautiously towards her friend. Gemma turned around in time to see her and laughed at Amelias facial expression. Both girls walked towards the building, laughing. Suddenly, Gemma stopped. Oh my..., someone in the crowd began. Amelia pushed her way through the crowd to see a student whose back was turned. At first, she was confused, not knowing why everyone was freaking out over a student not facing them, but then she took a closer look at the student. She was not standing up, her body was hanging, as if she was dead, but the girl was very much alive and even started speaking. Amelia only heard the word, remember. She turned to Gemma, who was in a trance. Gemma quickly snapped out of it and Amelia ran towards her friend. Does she...have wings? Or what are those? Gemma asked confusedly. Amelia stared at Gemma. No shes hanging but is somehow fine. The girls exchanged scared faces. But when they turned back towards the girl, she was gone and the students were walking away as if nothing had happened. They both slowly walked towards the school building, avoiding the area where the girl had stood. What do you think?
