If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complementary? If so, can you determine the angles? Explain how you know.

Answers

Answer 1

Answer:

i. Two angles can be vertical and supplementary.

ii. Yes, we can determine the angles.

Step-by-step explanation:

When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to 180 degrees .

It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is 90 degrees .

Equation practice with angle addition

Answers

Answer:

m<BOC = 60°

Step-by-step explanation:

First, we will need to determine the value of x

m<BOC + m<AOB = m<AOC (angle addition postulate)

Substitute

9x + 42 + 7x + 30 = 104

Collect like terms

16x + 72 = 104

16x + 72 - 72 = 104 - 72

16x = 32

x = 32/16

x = 2

✔️m<BOC = 9x + 42

Plug in the value of x

m<BOC = 9(2) + 42

m<BOC = 18 + 42

= 60°

Step-by-step explanation:

> sum of interior angles of a polygon is (n-2)·180°, where n-is the number of sides, so our rhombus has sum of angles =(4-2)·180° =360°

>we know that the opposite angles are congruent so ...

>we have the sum of interior angles is

108+108+7y-5+7y-5 = 360, combine like terms

14y +206 =360, subtract 206 from both sides

14y = 154, divide both sides by 14

y= 11

>the sides are congruent therefore

4x+17 = 8x-3 , subtract 4x, and add 3 from both sides

17+3 =8x-4x, combine like terms

Answers

Answer:

The perimeters are in the same ratio as the corresponding sides.

Step-by-step explanation:

There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say,  7:4  (or 7/4).  Then the perimeters are in the same ratio,  7:4.

Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.

B. y=x + 10

Answers

C. y = 3x - 4

Step-by-step explanation:

Given coordinates:

(2, 2), (3, 5), (5, 11), (7, 17)

The equation of any straight line is

y = mx + c

Where

m = Gradient

c = Constant

Gradient = y2 - y1/x2 - x1

Substitute any two values of y with the respective values of x.

Gradient = 17 - 2/7 - 2

= 15/5

= 3

Substitute the gradient into the general formula.

y = 3x + c

Substitute any value of the coordinate to the equation

2 = 3(2) + c

2 = 6 + c

c = -4

From y = mx + c,

substitute the values of m, the gradient, and c, the constant.

y = (3)x + (-4)

y = 3x - 4

Helen rented a kayak at the lake. There is a charge of $10 as an initial fee and then $2 an hour for every hour that she uses the kayak. If the total charge is $22 , how many hours did she kayak?

Answers

Answer:

She kayaked for 6 hours.

Step-by-step explanation:

If $10 is the initial fee, subtract $22 - $10 = $12.

If it charges $2 per hour, divide $12 by $2 which equals 6 hours.

Answer:

6 hours

Step-by-step explanation:

Cost = fee + charge per hour * number of hours

22 = 10 +2h

Subtract 10 from each side

22-10 = 10+2h-10

12 = 2h

Divide

12/2 = 2h/2

6 = h

Solve for x: 1.5x - 8 = 7
PLS ANSWER

Answers

Answer:

x = 10

Step-by-step explanation:

1.5x - 8 = 7

=> 1.5x = 7 + 8

=> 1.5x = 15

[tex] = > \frac{15x}{10} = 15[/tex]

[tex] = > x = 15 \times \frac{10}{15} [/tex]

=> x = 10 (Ans)

Answer:

x=10

Step-by-step explanation:

Simplifying

1.5x + -8 = 7

Reorder the terms:

-8 + 1.5x = 7

Solving

-8 + 1.5x = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 1.5x = 7 + 8

Combine like terms: -8 + 8 = 0

0 + 1.5x = 7 + 8

1.5x = 7 + 8

Combine like terms: 7 + 8 = 15

1.5x = 15

Divide each side by '1.5'.

x = 10

Simplifying

x = 10

The height, h metres, of a springboard diver above the surface of the water t seconds after she leaves the board is given by h=-5t-12+7. Find the maximum height reached by the diver? How long does it take for the diver to reach maximum height? Find the height of the diving board?

Answers

Answer:

[tex]h_{max} = 14.2m[/tex]

[tex]t = 1.2[/tex]

The height of the diver is 7m

Step-by-step explanation:

Given

[tex]h(t) =-5t^2 + 12t + 7[/tex]

Solving (a): The maximum height reached

First, we calculate the time to reach the maximum height using:

[tex]t = - \frac{b}{2a}[/tex] --- maximum of a function

Where

[tex]a = -5; b = 12; c = 7[/tex]

So, we have:

[tex]t = -\frac{12}{-2 * 5}[/tex]

[tex]t = \frac{12}{10}[/tex]

[tex]t = 1.2[/tex]

So, the maximum height is:

[tex]h(t) =-5t^2 + 12t + 7[/tex]

[tex]h(1.2)=-5 * 1.2^2 + 12 * 1.2 + 7[/tex]

[tex]h(1.2)=14.2[/tex]

Hence:

[tex]h_{max} = 14.2m[/tex]

Solving (b): Time to reach maximum height

This has been calculated in (a)

[tex]t = 1.2[/tex]

Solving (c): Height of the board.

This can be calculated by setting [tex]t =0[/tex] --- i.e. the height of the diver before diving

So, we have:

[tex]h(t) =-5t^2 + 12t + 7[/tex]

[tex]h(0) = -5 * 0^2 + 12 * 0 + 7[/tex]

[tex]h(0) = 7[/tex]
