If A Triangle Has Three Sides With The Lengths 20, 16, And 12, What Are The Angles?

Answers

Answer 1

Answer:

angle a = 53.13°

angle b = 36.87°

angle c = 90°

Step-by-step explanation:

The following is one way to perform the calculation. It may not be the best way.

Calculates ∠A, ∠B, ∠C based on given a, b and c.

∠A = arccos(  b2 + c2 - a2 2bc )

= 0.9273 rad = 53.13° = 53.13°

∠B = arccos(a2 + c2 - b2 2ac )

= 0.6435 rad = 36.87° = 36.87°

∠C = arccos(a2 + b2 - c2 2ab )

= 1.5708 rad = π/2 = 90°

Allison lives 380 miles from her grandmother. She plans to drive to her grandmother's house for the weekend. She will drive an average of 60 miles per hour. Which equation represents the distance (d) Allison has left to drive after h hours?

A. D=380+60h

B. D=(380-60)h

C. D=380-60h

D. D=380h-60

Answers

Answer:

its b

Step-by-step explanation:

The equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

We're given that:

Allison lives 380 miles from her grandmotherShe will drive an average of 60 miles per hour. Distance that Allison has left to drive represented by 'd' (in miles) after h hours.

In 1 hour, she averagely covers 60 miles.

In h hours, she averagely covers [tex]60 \times h[/tex] hours

d = distance remaining for her to reach to her grandmother's home after h hours of driving

d = Total distance - distance traveled in h hours

d = 380 - 60×h

(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, so 60×h can be simply written 60h)

Thus, the equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h

The absolute value of the number 0.75 is 0.75 .

What is an absolute value?

Absolute value of a number is the distance value from zero without considering sign of a number. It is also represented as |x|, where x is any number.

Absolute value of a positive number is that same positive value. Distance of a positive number from zero is that positive number.

So absolute value of 0.75;

|0.75| = 0.75

given mtw=bgk find the values of x and y

Answers

Answer:

x = 12

y = 8

Step-by-step explanation:

to solve for x you would set up your equation:

4x - 3 = 45

then solve using algebra:

4x - 3 = 45

4x = 48

x = 12

to solve for y set up your equation as:

11y + 6 = 94

TO GET 94: you will need to subtract 41 and 45 from 180 to get 94.

(each triangle equals 180 and we need the 3rd measure)

solve the equation:

11y + 6 = 94

11y = 88

y = 8

A rectangular book measures 8 X 10. What is the length of its
diagonal?

Answers

Answer:

Length of the diagonals is

[tex] \sqrt{ {8}^{2} +{10}^{2} } = \sqrt{64 + 100} = \sqrt{164} =2\sqrt{41}\\ =\boxed{12.8\: units} [/tex]

12.8 units is the right answer.

The diagonal length of the rectangular book is 12.8 units.

What is rectangular?

A rectangle is "four sided polygon, having all the internal angles  is equal to 90 degree. The two sides of each corner is right angles".

According to the question,

The length of rectangle is 8 units and the breadth of rectangle is 10 cm.

To find diagonal of the rectangle: Using Pythagoras theorem a² + b² = c².

c = [tex]\sqrt{a^2 + b^2}[/tex]

  = [tex]\sqrt{8^2 + 10^2}[/tex]

  = [tex]\sqrt{64 + 100}[/tex]

  = [tex]\sqrt{164}[/tex]

  = 2[tex]\sqrt{41}[/tex]

  = 12.8 units

Hence, the diagonal length of the rectangular book is 12.8 units.
